Cadmium Sulfide (CdS)

Cadmium Sulfide is a yellow solid compound composed of Cadmium and Sulfur and has two morphologies one being hexagonal, and the other cubic. Both polymorphs of Cadmium Sulfide are piezoelectric and the hexagonal is also pyroelectric. CdS functions as a semiconductor, having a bandgap of about 2.42 eV, which places it in the category of wide bandgap semiconductors. Additionally, it exhibits strong photoconductivity, meaning its electrical conductivity increases upon exposure to light.

Furthermore, CdS is commonly deposited as a thin film in various electronic devices, using techniques like physical vapor deposition (PVD) and sputtering. Cadmium Sulfide serves as a pigment known as cadmium yellow in the art and painting industry due to its vibrant yellow color. Scientists are researching its potential in newer, more efficient solar cells and renewable energy technologies. In addition, CdS also finds use in non-linear optics due to its optical properties.
