Abstract

We describe briefly a cheap and non polluting technique to grow epitaxial GaAs layers, several hundred microns thick, in a matter of hour. Detectors consisting of a p+/i/n+ structure have been realised with these layers and we present their characteristics obtained from currentvoltage, capacitance-voltage measurements as well as their response versus the energy and flux of X-rays.
