Abstract
A new tunnelling model is described which treats the interfacial layer in a polysilicon emitter transistor as a wide bandgap semiconductor. Potential barriers are formed in the valence and conduction bands, the sizes of which vary with the dopant type and concentration in the interfacial layer.
