ABSTRACT:
A space-charge-limited (SCL) transistor is utilized as a photo-transistor. The preferred embodiments feature a base diffusion which is shallower than the standard SCL structure and a base geometry for increased light collection while maintaining the high current gain characteristic of SCL transistors.
