SbTe antimony telluride is a layered phase change material with exciting optical driven phase change properties. This vdW crystal exhibit rather unique crystalline properties (see atomic view images). While some preliminary studies have been conducted to date, it is quantum properties especially in the size confinement limit is largely unknown.
Our SbTe vdW crystals are synthesized using modified Bridgman technique using our own process parameters at unparalleled 99.9999% confirmed purity rates. Crystals are cut in c-axis, thus it is very easy to exfoliate onto desired substrates. Each order comes with large nearly centimeter size crystals.
