Abstract :
The effective surface recombination velocity is determined analytically for a doped polysilicon contact to the emitter of a bipolar transistor in the presence of a thin interfacial oxide layer. Results are presented for various doping levels, oxide thicknesses and barrier heights. The analysis considers both tunnelling and thermionic emission through the interface.
