Broad-band frequency characterization of double Y-branch nanojunction operating as room-temperature RF to DC rectifier

Room-temperature dc and broad-band high-frequency (HF) to dc conversion measurements of a double Y-branch junction (YBJ) are presented and discussed. Nonlinear dc characteristics of the devices at room temperature are observed and HF to dc conversion up to 40 GHz at room temperature is presented. The HF to dc conversion efficiency degradation is found to be partly due to losses in interconnects feeding the device. A small-signal equivalent circuit of the YBJ is proposed in order to verify the frequency dependence of intrinsic elements.
