Pseudo-metal-base transistor with high gain

We use evaporated C60 fullerene as emitter, a conducting polymer blend as base, and Si as collector in a vertical transistor structure similar to a metal-base transistor. The conducting polymer blend used as a base is poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate). The measured common-base current gain of our pseudo-metal-base transistor (p-MBT) is close to 1.0. The p-MBT is straightforward to fabricate and is compatible with conventional Si-based electronics.
