时间Fri Dec 17 21:31:16 2010
如题,
因为急需解出一份考题~~
希望有高手能帮帮我解答!!!
这是其中两题:
Q1: Define the following items in detail.
(a) primitive vector (b) Bravais lattice (c) reciprocal lattice
(d) Brillouin zone (e) density of state (f) energy band
Q2: Consider a 1d crystal with atoms regularly spaced in b.
Consider the tight-binding model where the atomic wave function
can be written as @(x - Ri), in which
Ri is the position of i^th atom. Assume
积分 @^*(x - Ri)H@(x - Ri) dx = -E0
积分 @^*(x - Ri)H@(x -Ri+1) dx = -V1
积分 @^*(x -Ri)H@(x -Ri+2) dx = -V2
1)Show Bloch wave function of the electron @k(r).
2)Calculate the band structure E(k)
3) Show the relation between effective mass and the band width at band bottom and
band edge.
希望高手能帮我解答!!!
感恩感恩!!
有意解其他题者,请来信!!!
小的愿付上p币报偿,或其他小的可以接受的范围~~
