Semiconductors

In semiconductors ? < 104 S/cm

In the equation: ? = n e ?

? increases with increase of temperature

n is exponentially dependent on temperature

n = N exp-?G/RT

Therefore, ? can increase rapidly with increase of temperature

Elemental Semiconductors: Si, Ge, grey Sn (white Sn and Pb are metals)

Compound Semiconductors: III-V compounds, GaAs and InSb

(Isoelectronic with Ge and Sn)
