Nettet3. apr. 2024 · LEDs are made up of compound semiconductors and not by the elemental conductor because the band gap in the elemental conductor has a value that can detect the light of a wavelength which lies in the infrared (IR) region. In elementary semiconductors numbers of free electrons are very small leading to negligible conduction. Nettet16. nov. 2024 · LED light bulbs are made of various types of light-emitting material such as silicon, tin, tungsten, aluminum, copper, indium, or tin oxide. Light-emitting material has the ability to glow in certain light conditions. There are different types of light-emitting materials and the same is true for LED light bulbs.

NettetThe type of material for UV LED is AlGaN, which will have a layer of aluminum grown on top of GaN on either Sapphire or SiC substrate. Aluminum as metal is conductive, but on AlGaN it is not. To get to a far UV band like 222nm, high density of aluminum needs to grow, which becomes non-conductive.
