In this work, by means of Monte Carlo simulations, we analyze the presence of a resonance in the high-frequency response of an asymmetric nonlinear nanodiode. This device exhibits a tunable-by-geometry resonant DC current response to AC voltage excitations in the THz range. The resonance is linked to a noise mechanism: collective charge fluctuations in the space-charge region around the active channel of the device, which are visible both in noise and rectification. This effect, present at room temperature, could be useful for selective THz detection.
