Abstract

The invention discloses a one-dimensional tin selenide nanoarray as well as a preparation method and an application thereof. The one-dimensional tin selenide nanoarray consists of tin selenide nanowires growing in the same direction and arranged in an array form. The one-dimensional tin selenide nanoarray is prepared by depositing tin selenide as a raw material under the action of a catalyst with a chemical vapor deposition method, is applicable to NTC (negative temperature coefficient) thermistors and has an excellent negative temperature coefficient. The preparation method of the one-dimensional tin selenide nanoarray has the advantages of low cost, simple synthesizing step, high speed, good crystallinity and controllable morphology.

Description

technical field

[0001] The invention relates to the technical field of inorganic compound semiconductor nanomaterials, in particular to a one-dimensional tin selenide nanoarray, its preparation method and application. Background technique

[0002] Due to their unique physical and chemical properties, binary IV-VI compounds have potential application prospects in phase change memories, topological insulators, field effect transistors, thermoelectric and multi-exciton photovoltaic cells, and have been widely studied recently. Among them, tin selenide (SnSe) is an important p-type semiconductor compound. At room temperature, the direct band gap of the bulk material is 1.3eV, and the indirect band gap is 0.9eV. Due to its unique layered structure, abundant reserves, environmental friendliness and chemical stability, it has recently attracted a lot of research interest from scientists.

[0003] Due to the high specific surface area and high sensitivity of nanomaterials, the prep...
