Abstract

The invention discloses a device capable of producing a photoelectric effect and electroluminescence simultaneously and a preparation method thereof. The photoelectric device is acquired through packaging a cadmium sulfide/cadmium telluride heterogeneous junction nano-rod, and specifically comprises an anisotropic conductive film, an Al electrode, ZnO, a heterogeneous junction nano-rod, 2, 3, 5, 6-tetrafluoro-7, 7', 8, 8'-tetracyanoquinodimethane, TCNQF4 and the like. The invention further discloses a preparation method of the photoelectric device.

Description

technical field [0001] The invention relates to the field of semiconductors, in particular to a device capable of producing photoelectric effect and electroluminescence simultaneously and a preparation method thereof. Background technique [0002] Since nanomaterials, especially quantum dots and nanoheterojunctions, have different energy band structures from bulk materials, they have great application potential in the field of optoelectronics. For example, Chinese invention patent CN103943733A discloses a preparation method of an LED ultra-parallel light source based on vertical nanowires. The light source uses a Si-CdS heterogeneous pn junction of vertical silicon nanowires, and the microlens uses a concave mirror. The preparation method specifically includes: first preparing a dot mask to determine the size of the silicon nanowire; then using ICP-RIE dry etching technology to prepare the silicon nanowire; and thermally oxidizing the silicon nanowire to remove part of the o...
