Fabrication of novel unipolar nanodiodes in InAs/AlSb for microwave detection

• Abstract—We report on the fabrication of unipolar nanodiodes into an InAs/AlxGa1-xSb quantum-well heterostructure for room temperature microwave detection up to 110 GHz. Electron-beam lithography was combined with both dry- and wet-etching, and we explored the differences in the electric and detection parameters with the two methods.
