Chapter 2-3. States and carrier distributions
So far we have concentrated on carrier properties of qualitative
nature. We also need to:
Determine the carrier distribution with respect to energy in
Determine the quantitative information of
Chapter 2-4. Equilibrium carrier concentrations
Equilibrium electron concentration is given by:
Equilibrium hole concentration is given by:
This integral cannot be solved in closed form, but we can make
some approximations to get a closed-form solution.

1. (a) Solve the stationary Schrodinger equation for the harmonic oscillator potential and find the stationary eigenstates for this system.
(b) Find the e
In this problem we make use of writing operator x and p in terms of the raising and

hpi = i
(x)(a+ +a ) (x)dx;
Chapter 2-2. Carrier properties
Mass like charge is a very basic property of electrons and holes.
The mass of electrons in a semiconductor may be different than its
mass in vacuum.
Effective mass concept
Electrons moving inside a semicon
