· PdSe

PdSe is a narrow-bandgap semiconductor compound composed of palladium and selenium, belonging to the transition metal chalcogenide family. This material is primarily of research and emerging-technology interest, investigated for optoelectronic and quantum applications where its tunable electronic properties and potential for heterostructure integration offer advantages over conventional semiconductors. Its notable characteristics within the chalcogenide class include relatively high carrier mobility and compatibility with 2D device architectures, making it a candidate for next-generation photodetectors, thermoelectrics, and quantum computing platforms.
