• We demonstrate fundamental oscillations at around 900 GHz with low bias voltages in resonant tunnelling diodes (RTDs) having spike-doped structures. The voltages at the current peak were 0.67 and 0.4 V for RTDs with the spike-doping concentrations of 2 × 10^<18> and 1 × 10^<19> cm^<-3>, respectively, and 0.94 V for the RTD without spike doping. The peak current densities were around 18 mA/μm^2 and remained almost unchanged even after the spike doping. The highest oscillation frequency observed in this study was 898 GHz in the 0.53-μm^2-mesa area for the RTD with a spike-doping concentration of 2 × 10^<18> cm^<-3>.
