By completing the Periodic Potential Lab in ABACUS - Assembly of Basic Applications for Coordinated Understanding of Semiconductors, you will be able to:
a) understand the Kronig-Penney model and the formation of energy bands and energy gaps due to the underlying periodic interaction potential
b) understand the concept of the effective mass
c) create your own Kronig-Penney solver.
The specific objectives of the Periodic Potentials Lab are:
If you have not had experience with periodic potentials, bandstructure, the concept of the effective mass, etc., listed below are the suggested reading materials:
1. D. K. Ferry, Quantum Mechanics: An Introduction for Device Physicists and Electrical Engineers, Second Edition (Institute of Physics Publishing, 2001).
