Theoretical Foundations of Charge Transport

Charge transport in semiconductor is primaryly described by by models such as drift anddifusion. These models explain how contrains andd holes move undeid electric fields andd concentration gradients. The drift concurt results from the force experted by an electric field, while diffusion events due to concentration differences.
