About PdSe2 (Palladium diselenide)

Palladium diselenide (PdSe₂) is a layered transition metal dichalcogenide (TMD) that has recently gained attention in the realm of materials science. Its unique electronic and optical properties make it a candidate for various applications. In particular, PdSe₂ has shown promise in photodetector devices due to its ability to absorb a broad range of light wavelengths. Additionally, its anisotropic structure enables the exploration of novel physical phenomena, which could be beneficial for future electronic and optoelectronic applications. Researchers continue to study PdSe₂ to understand its full potential better and realize its integration into devices. Mineral: Verbeekite
