Low and room temperature studies of RF to DC rectifiers based on ballistic transport

We report on DC and broadband HF to DC conversion measurements of a Double Y-branch junction. Nonlinear DC characteristics of the devices are observed and HF to DC conversion up to 50 GHz at 77 K and at room temperature is presented. The HF to DC conversion efficiency degradation at high frequencies is found to be partly due to losses in interconnects feeding the device.
