Abstract

A functional material with a CuO and In2O3 micro-nano heterogeneous periodic structure of the invention and a preparation method thereof belong to the technical field of semiconductor heterostructure material. The functional material is assembled from bump portions and pit portions in periodic alternation; a bump portion is formed by stacking of nano CuO, and a pit portion is formed by stacking of nano In2O3; and a bump CuO and an adjacent In2O3 pit constitute a period. The preparation method comprises the steps of: precipitating Cu2O and In(OH)3 alternately under effect of square wave potential in a solution containing nitrates; and carrying out high temperature treatment on the Cu2O and In(OH)3 to obtain the material with CuO and In2O3 heterogeneous periodic structure. The functional material prepared by the invention has excellent optical, electrical and gas sensitive properties and high stability; and the heterostructure material with different periods prepared by growth voltages with different frequencies has characteristics of controllable growth area and adjustable periodicity.

Description

technical field

[0001] The invention belongs to the technical field related to semiconductor heterostructure functional materials, and relates to the method of electrochemical deposition to prepare In 2 o 3 And related technologies of CuO micro-nano heterogeneous periodic structure functional materials. Background technique

[0002] Functional nanomaterials have always been concerned by people, especially the preparation of semiconductor micro-nano heterostructure materials with good photoelectric and gas-sensing properties is the current research focus. A semiconductor heterostructure is a structure that combines two different types of semiconductor materials. The electronic behavior in this structure, including light irradiation, temperature, and the interaction between gas and electrons, and other physical properties are similar to those of a single semiconductor material. obviously different. In recent years, the research on many semiconductor oxide functional materia...
