[來源]考古題

[題目]
1.It is well-known that there are about 1022 ~ 1023 atoms/cm3.
However, the most text generally describes the solid properties
by one electron approximation. Please discuss the discrepancy. (10%)

2.What is the Bloch theorem? What is the importance of this theorem
 for solving the Schrodinger’s equation? (10%)

3.Why do the solid state physicists have to know the band structures of solids?
Please describe the nearly free electron model and the tight-binding model,
respectively. If the nearly free electron model of the band is rough,
why do we learn it? (10%)

4.What is the density of states? What is the importance of the
density of states for electronic materials? (10%)

5.Please describe the effective masses of the materials as possible as you can.
Why are they different? (10%)

6.How do we discuss the optical properties of materials in the atomistic way?
Please explain what are Fermi golden rule, interband transition,
and intraband transition, respectively? (10%)
