What is TIN SELENIDE?

Description

Tin selenide (SnSe) is a narrow band gap semiconductor comprised of environmentally friendly and earth abundant elements.

What are the applications of Application

Exfoliated few-layer tin selenide (SnSe) has been used in the field of photovoltaics and infrared optoelectronic devices, radiation detectors, holographic recording systems, electrical switching, and polarity-dependent memory switching devices. SnSe also has great potential for use in memory switching devices, efficient solar materials, and holographic recording systems.

Synthesis

Tin?selenide?(SnS)?is manufactured using chemical vapour transport (CVT) crystallisation, with crystals having a high purity (in excess of 99.999%).

Preparation

Synthetic?- chemical vapour transport (CVT)

Chemical properties

3–12mm pieces with 99.999% purity; steel gray prisms [MER06] [CER91]

The Uses of TIN SELENIDE

Tin selenide finds application in low- cost photovoltaics devices and memory-switching devices. It acts as a solid-state lubricant. It is also used for solar cells and anodes for lithium-ion batteries. Further, it is a narrow band-gap semiconductor.
