Hydrogenated amorphous silicon (a-Si:H) is a non-crystalline form of silicon that has been widely used in the production of solar cells and thin-film transistors due to its ability to be deposited at low temperatures on a variety of substrates. Its electronic properties are significantly influenced by the presence of hydrogen, which passivates dangling bonds and improves the material's electrical characteristics.

Thin-film transistors (TFTs) are a type of field-effect transistor made by depositing thin films of an active semiconductor layer as well as the dielectric layer and metallic contacts over a supporting substrate. They are crucial components in modern display technologies, such as liquid crystal displays (LCDs) and organic light-emitting diode (OLED) displays, due to their ability to control pixel illumination with high precision and low power consumption.

Electronic properties refer to the behavior and characteristics of electrons in materials, which determine a material's electrical conductivity, band structure, and other related phenomena. Understanding these properties is crucial for the development of electronic devices and materials science innovations.
