Engineering semiconductor nanowires for photodetection: From visible to terahertz

Joyce, Hannah; Alexander-Webber, Jack A.; Peng, Kun; Johnston, Michael B.; Parkinson, Patrick; Tan, Hark Hoe; Jagadish, Chennupati


III-V semiconductor nanowires combine the properties of III-V materials with the unique advantages of the nanowire geometry, allowing efficient room temperature photodetection across a wide range of photon energies, from a few eV down to meV. For example, due to their nanoscale size, these show great promise as sub-wavelength terahertz (THz) detectors for near-field imaging or detecting elements within a highly integrated on-chip THz spectrometer. We discuss recent advances in engineering a...[Show more]
