InSe Crystals

InSe Crystals

InSe (γ-phase Indium Selenide) is a layered van der Waals semiconductor that exhibits remarkable optoelectronic, electronic, and thermoelectric properties. It features a tunable bandgap, high carrier mobility, and strong light absorption, making it highly suitable for applications in photodetectors, field-effect transistors (FETs), photovoltaics, and nonlinear optics. Our InSe (γ-phase) crystals are synthesized using the Chemical Vapor Transport (CVT) method, ensuring high purity, superior crystallinity, and well-controlled stoichiometry.
