Everyone is familiar with the amazing performance of a modern smartphone, powered by a billion-plus nanotransistors, each having an active region that is barely a few hundred atoms long. The same amazing technology has also led to a deeper understanding of the nature of current flow and heat dissipation on an atomic scale which is of broad relevance to the general problems of non-equilibrium statistical mechanics that pervade many different fields. This book is based on a set of two online courses originally offered in 2012 on nanoHUB-U and more recently in 2015 on edX. In preparing the second edition the author decided to split it into parts A and B titled Basic Concepts and Quantum Transport respectively, along the lines of the two courses. A list of available video lectures corresponding to different sections of this volume is provided upfront. To make these lectures accessible to anyone in any branch of science or engineering, the author assume very little background beyond linear algebra and differential equations. However, the author will be discussing advanced concepts that should be of interest even to specialists, who are encouraged to look at his earlier books for additional technical details.

The transistor is the key enabler of modern electronics. Progress in transistor scaling has pushed channel lengths to the nanometer regime where traditional approaches to device physics are less and less suitable. These lectures describe a way of understanding MOSFETs and other transistors that is much more suitable than traditional approaches when the critical dimensions are measured in nanometers. It uses a novel, “bottom-up approach” that agrees with traditional methods when devices are large, but that also works for nano-devices. Surprisingly, the final result looks much like the traditional, textbook, transistor models, but the parameters in the equations have simple, clear interpretations at the nanoscale. The objective is to provide readers with an understanding of the essential physics of nanoscale transistors as well as some of the practical technological considerations and fundamental limits. This book is written in a way that is broadly accessible to students with only a very basic knowledge of semiconductor physics and electronic circuits. Complemented with online lecture by Prof Lundstrom: nanoHUB-U Nanoscale Transistor Contents:MOSFET Fundamentals:OverviewThe Transistor as a Black BoxThe MOSFET: A Barrier-Controlled DeviceMOSFET IV: Traditional ApproachMOSFET IV: The Virtual Source ModelMOS Electrostatics:Poisson Equation and the Depletion ApproximationGate Voltage and Surface PotentialMobile Charge: Bulk MOSMobile Charge: Extremely Thin SOI2D MOS ElectrostaticsThe VS Model RevisitedThe Ballistic MOSFET:The Landauer Approach to TransportThe Ballistic MOSFETThe Ballistic Injection VelocityConnecting the Ballistic and VS ModelsTransmission Theory of the MOSFET:Carrier Scattering and TransmissionTransmission Theory of the MOSFETConnecting the Transmission and VS ModelsVS Characterization of Transport in NanotransistorsLimits and Limitations Readership: Any student and professional with an undergraduate degree in the physical sciences or engineering.

This book aims to serve as a practical guide for novices to design and conduct measurements of thermal properties at the nanoscale using electrothermal techniques. An outgrowth of the authors�â�€�™ tutorials for new graduate students in their own labs, it includes practical details on measurement design and selection, sensitivity and uncertainty analysis, and pitfalls and verifications. The information is particularly helpful for someone setting up their own experiment for the first time. The book emphasizes the integration of thermal analysis with practical experimental considerations, in order to design an experiment for best sensitivity and to configure the laboratory instruments accordingly. The focus is on the measurements of thermal conductivity, though thermal diffusivity and thermal boundary resistance (thermal contact resistance) are also briefly covered, and many of the principles can be generalized to other challenging thermal measurements. The reader is only expected to have the basic familiarity with electrical instruments typical of a university graduate in science or engineering, and an acquaintance with the elementary laws of heat transfer by conduction, convection, and radiation.

Noch hat das Motto “Alles muss kleiner werden” nicht an Faszination verloren. Physikern, Ingenieuren und Medizinern erschließt sich mit der Nanotechnologie eine neue Welt mit faszinierenden Anwendungen. E.L. Wolf, Physik-Professor in Brooklyn, N.Y., schrieb das erste einführende Lehrbuch zu diesem Thema, in dem er die physikalischen Grundlagen ebenso wie die Anwendungsmöglichkeiten der Nanotechnologie diskutiert. Mittlerweile ist es in der 3. Aufl age erschienen und liegt jetzt endlich auch auf Deutsch vor. Dieses Lehrbuch bietet eine einzigartige, in sich geschlossene Einführung in die physikalischen Grundlagen und Konzepte der Nanowissenschaften sowie Anwendungen von Nanosystemen. Das Themenspektrum reicht von Nanosystemen über Quanteneff ekte und sich selbst organisierende Strukturen bis hin zu Rastersondenmethoden. Besonders die Vorstellung von Nanomaschinen für medizinische Anwendungen ist faszinierend, wenn auch bislang noch nicht praktisch umgesetzt. Der dritten Aufl age, auf der diese Übersetzung beruht, wurde ein neuer Abschnitt über Graphen zugefügt. Die Diskussion möglicher Anwendungen in der Energietechnik, Nanoelektronik und Medizin wurde auf neuesten Stand gebracht und wieder aktuelle Beispiele herangezogen, um wichtige Konzepte und Forschungsinstrumente zu illustrieren. Der Autor führt mit diesem Lehrbuch Studenten der Physik, Chemie sowie Ingenieurwissenschaften von den Grundlagen bis auf den Stand der aktuellen Forschung. Die leicht zu lesende Einführung in dieses faszinierende Forschungsgebiet ist geeignet für fortgeschrittene Bachelor- und Masterstudenten mit Vorkenntnissen in Physik und Chemie. Stimmen zur englischen Vorauflage „Zusammenfassend ist festzustellen, dass Edward L. Wolf trotz der reichlich vorhandenen Literatur zur Nanotechnologie ein individuell gestaltetes einführendes Lehrbuch gelungen ist. Es eignet sich – nicht zuletzt dank der enthaltenen Übungsaufgaben – bestens zur Vorlesungsbegleitung für Studierende der Natur- und Ingenieurwissenschaften sowie auch spezieller nanotechnologisch orientierter Studiengänge.“ Physik Journal „... eine sehr kompakte, lesenswerte und gut verständliche Einführung in die Quantenmechanik sowie ihre Auswirkungen auf die Materialwissenschaften ...“ Chemie Ingenieur Technik

Studienarbeit aus dem Jahr 2012 im Fachbereich BWL - Marketing, Unternehmenskommunikation, CRM, Marktforschung, Social Media, Note: 3,0, Universität Hamburg (Sozialökonomie), Veranstaltung: Multichannelmarketing, Sprache: Deutsch, Abstract: Heut zu Tage gewinnen alternative Vertriebswege immer mehr an Bedeutung. Dieses liegt zum einen an den sich verändernden Kaufgewohnheiten der Konsumenten, da „die Ver-braucher ihre Beschaffungskanäle nach der Bequemlichkeit und Verfügbarkeit der Produk-te aussuchen“ , und zum anderen unterliegen die vom Handel angebotenen Betriebsformen einem signifikanten Wandlungsprozess. Neue Absatzkanäle, wie beispielsweise der Absatz von Produkten in Sportstadien oder Shop-in Shop-Lösungen, werden eingesetzt bzw. aus-gebaut. Der Vertrieb über das Medium Internet wurde durch die Entwicklung der Informa-tions- und Kommunikationstechnologien ermöglicht und wird zunehmend als Absatzkanal eingesetzt. Der Einsatz elektronischer Medien, wie zum Beispiel des Internets, als alternativen Ver-triebsweg wird als E-Commerce bezeichnet. Der Begriff E-Commerce wird definiert als „die elektronische Unterstützung, die in direktem Zusammenhang mit dem Kauf und Ver-kauf von Gütern und Dienstleistungen via elektronischer Netze in Verbindung stehen." Dabei wird der Begriff E-Commerce in einem sehr weiten Verständnis verwendet. Oft zählt schon das auf einen Verkauf zielende Informationsangebot im Web zum E-Commerce oder auch die Unterstützung interner Geschäftsprozesse durch Informations- und Kommunikationstechnologien.

This work provides an interpretation of John Stuart Mill’s On Liberty (1859) and elucidates the fundamental principles of Mill’s concept of liberty. For Mill, the right to form one’s own convictions and live according to them should only be infringed upon for one reason, namely “to prevent harm to others”.
