The design and fabrication on gate type resonant tunneling transistor

Abstract

In light of fabricating resonant tunneling diode (RTD), in this paper a GaAs-based resonant tunneling transistor with gate structure (GRTT) has been designed and fabricated successfully. A systematic depiction centers on the designs of material structure, device structure, photolithography mask, fabrication of device and the measurement and analysis of parameters. The fabricated GRTT has a maximum PVCR of 46 and a maximum transconductance of 8 mS. The work lays the foundation for further improvement on the performance and parameters of RTT.
