Indium(iii) selenide is a type of material that is made up of indium, selenium and sometimes a little bit of impurities too. It is usually in the form of a solid and it looks like a bunch of tiny crystals that are all stuck together.
This material is a type of semiconductor which means that it has some electrical properties that allow it to be used in things like electronic devices. Semiconductors are really important because they help control the flow of electricity in electronic devices like computers, phones, and other similar gadgets.
Indium(iii) selenide is actually really useful because it can change its properties in response to different types of energy like light, heat, or electricity. This quality makes it really valuable in things like solar cells and other types of energy related technologies.
Overall, indium(iii) selenide is a really neat material that scientists and engineers use to make amazing devices that help us in our everyday lives.
