CdTe nanoflake arrays on a conductive substrate: template synthesis and photoresponse property

CdTe nanoflake arrays were fabricated directly on a conductive substrate via gas-phase tellurization of a cadmium nanoflake template. A put-in-heating technique was developed to prevent the fusion and collapse of the cadmium template, as a result, the nanoflake morphology was well preserved during high temperature tellurization. A simple photoresponse device based on CdTe nanoflake arrays was assembled and exhibited high performance, indicating that CdTe nanoflake arrays are promising for photoelectrical applications.
