Abstract
A high performance AlAs/In0.53Ga0.47As/InAs resonant tunneling diode (RTD) on InP substrate is fabricated by inductively coupled plasma etching.This RTD has a peak-to-valley current ratio (PVCR) of 7.57 and a peak current density Jp=39.08kA/cm2 under forward bias at room temperature.Under reverse bias,the corresponding values are 7.93 and 34.56kA/cm2.A resistive cutoff frequency of 18.75GHz is obtained with the effect of a parasitic probe pad and wire.The slightly asymmetrical current-voltage characteristics with a nominally symmetrical structure are also discussed. -
