This is a self-study project on solving the Schrodinger equation numerically. It starts from the simplest textbook case I could check by hand and builds up, one new idea at a time, to a problem I ...

Effective mass (m*) is defined as: where x, y, z are the directions in the reciprocal Cartesian space (2π/A), En(k) is the dispersion relation for the n-th electronic band. The explicit form of the ...
