Lecture 5 – How Do We Tailor and Control Electronic Properties?

The incorporation of strain offers one more parameter for band tailoring. We discuss how strain modifies degeneracies, effective masses, bandgaps, eigenstates at the bandedges..

Lecture 8 – Transport in Small Structures

Transport in “small” systems is discussed. Transport can be coherent. Number of electrons involved could be very small (countable). Capacitance could be very small. These create new types of transport and potentially new devices.
