[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%)
[瓶頸] (寫寫自己的想法，方便大家為你解答)
希望大家能幫我解答一下...因為是期中考，所以希望能詳細一點!
可以寄B信給我...非常感恩大大的幫忙@@"
拜託麻煩各位了!
謝謝....<(、_____、)>
