PdSe₂ Crystals

Description

PdSe₂ Crystals (Palladium Diselenide)

PdSe₂ is a layered transition metal dichalcogenide (TMD) known for its unique pentagonal crystal structure and tunable electronic properties. Unlike typical TMDs, PdSe₂ exhibits a transition from semimetallic behavior in bulk to semiconducting properties in monolayer form. It also features high carrier mobility, excellent environmental stability, and strong anisotropic optical and electrical characteristics, making it highly suitable for applications in nanoelectronics, optoelectronics, sensing, and energy-related devices. Our PdSe₂ crystals are synthesized using the Chemical Vapor Transport (CVT) method, ensuring high purity, precise stoichiometry, and superior crystallinity.
