Cd1-xZnxTe(x ∼ 0.04) poly-crystalline films with a thickness of less than 300 μm are grown on an ITO/glass substrate by physical vapor transport method, and the films are evaluated as a detector for radial rays. A reservoir chamber containing CdCl2 powders is provided at one end of the growth tube for obtaining films with high electrical resistance and for reducing the leakage current of the device. A relation between the growth conditions and the characteristics of the grown film is clarified, and the film grown under one of the suitable conditions shows sensitivity to radial rays.
