Dear Tram
I am afraid that your question cannot be answered in a short e-mail... I can 
suggest you to read at least one among many semiconductor physics books.
a quite simple, application oriented one is 

B. G. Streetman
Solid State electronic devices
Prentice-Hall International editions

But you can surely find plenty of alternatives...
