|
conduction electrons
|
electrons free to move throughout the solid that are in high numbers in metals
|
|
|
valence electron
|
electrons loosely bound to the atom designated by Z -- in metals all valence electrons become conduction electrons
|
|
|
core electrons
|
tightly bound to the atom
|
|
|
density (n) of conduction electrons
|
n = [(# atoms in crystal structure(sc=1, bcc=2, fcc=4)*Z]/a^3
|
|
|
drift velocity
|
Vd = <r>/t average velocity of electron = 1/2 a *t^2/thao
Vd = -(e*thao/m)E pg38 |
