New Publication – Distinguishing cap and core contributions to the photoconductive terahertz response of single GaAs based core–shell–cap nanowire detectors

corecap.pngOur recent work on single-nanowire terahertz detectors has been published in a special issue of the Lithuanian Journal of Physics, celebrating the 70th birthday of Prof. Arunas Krotkus.

In this work, Dr Kun Peng used single-nanowire terahertz detectors with different capping to understand the relative contribution of the core and cap to the detected THz signal. By tuning the cap to be thicker, it is possible to engineer these detectors to have shorter carrier lifetimes and as a result, to exhibit direct THz field detection.
