Question
Using the concept of electron and hole current, write an expression for the conductivity of a semiconductor.
Solution
The conductivity of a semiconductor,
σ = ne eμe + nh eμh.
where,
ne is the number of electrons,
e is the electronic charge,
and is the mobility of electron and hole respectively.
σ = ne eμe + nh eμh.
where,
ne is the number of electrons,
e is the electronic charge,
and is the mobility of electron and hole respectively.
