An alternative to the transistor for high-frequency detector applications is the two-terminal self-switching diode (SSD). The SSD is based on a nanometer-wide channels and a lateral gate connected to a drain. SSDs with In65Ga35As channels were fabricated and characterized. The design was optimized for low noise detection. In on-wafer measurements 2-315 GHz, a responsivity >150 V/W and noise-equivalent power (NEP) 50-100 pW/Hz½ was measured with a 50 Ω source. In the measured frequency range, this is the lowest NEP for SSDs demonstrated.
