Lecture 2: General Model for Transport
28 Jul 2011 | | Contributor(s):: Mark Lundstrom
Datta's model of a nanodevice is introduced as a general way of describing nanodevices as well, as bulk metals and semiconductors.
Lecture 3: Resistance-Ballistic to Diffusive
The resistance of a ballistic conductor and concepts, such as the quantumcontact resistance, are introduced and discussed. The results are then generalized to treat transport all the way from the ballistic to diffusive regimes.
Lecture 4: Thermoelectric Effects-Physical Approach
The effect of temperature gradients on current flow and how electrical currents produce heat currents are discussed.
Near-Equilibrium Transport: Fundamentals and Applications
Engineers and scientists working on electronic materials and devicesneed a working knowledge of "near-equilibrium" (also called "linear"or "low-field") transport. The term "working knowledge" meansunderstanding how to use theory in practice. Measurements ofresistivity, conductivity, mobility,...
