文摘
CdTe nanorod arrays on ITO have been demonstrated using a catalyst-free thermal evaporation method. Despite the stacking faults observed in the nanorods, they show intense near band edge emission at 1.5 eV with a narrow full width at half-maximum of 79 meV and negligible deep-level emission during the room temperature photoluminescence measurement. The device based on the aligned array-on-ITO configuration demonstrates excellent photoresponse to the visible light, which is ascribed to the large absorption coefficient of the material and also suggests good electronic structure quality of the nanorods.
