Abstract:
1. A method for forming a detector sensitive to ionizing radiation, comprising the steps of: a) etching a surface of a CdZnTe crystal with a solution of bromine in methanol; b) growing a dielectric layer on said etched surface forming thereby a passivated surface; c) applying a photoresist layer onto said dielectric layer; d) exposing a portion of said photoresist using electromagnetic radiation and a lithography means; e) developing and removing said exposed portion thereby creating an image pattern in said photoresist and exposing a corresponding portion of said passivated surface; f) removing said corresponding portion of said passivating surface and thereby replicating said image onto said CdZnTe crystal surface; g) depositing a metal conductor onto said surface image thereby forming an electrode on said exposed CdZnTe crystal surface; and h) removing the remaining photoresist layer.
