In summary, ultra-thin ZnTe semiconductor nanosheets have been successfully synthesized through the space-confined physical vapour deposition method. The nanosheets are high quality crystallized, with the thickness can be as thin as 65 nm. Typical p-type conductivity of the ZnTe nanosheets has been demonstrated, and the constructed PDs based on the ZnTe nanosheets exhibit a high photoresponsivity and good stability. These as-synthesized ZnTe nanosheets with novel electrical properties represent
