Abstract
Detectors for X-rays, ions and electrons play a significant role in the analytical instruments (e.g. SEM, TEM, SIMS, MALDI-TOF). Our team discovered that certain 1-D nanostructures exhibited efficient secondary electron emission (SEE) when bombarded by X-rays, ions and electrons.1 SEE is a key factor to determine the efficiency of detectors under various irradiations. Heterostructure nanowires are very promising for the development of most-sought after universal radiation detectors.2 The project is aimed at developing nanomaterials for universal efficient radiation detectors which expected to have multi-million dollars market.
