Description
World's only flux zone high quality and purity HfTe5 crystals. We offer HfTe5 in flux or CVT growth techniques depending on your choice.
HfTe5 is a layered transition metal pentatelluride that crystallizes in the orthorhombic phase and shows a perfectly layered structure. It lies at the boundary between weak and strong topological insulators and may transition to a Dirac semimetal. Under hydrostatic pressure, it can become superconducting.
We offer the largest size crystals in academic or commercial domain. These crystals are ideal for exfoliation and large-area monolayer production. While bulk crystals are stable in air, monolayers oxidize readily to TeO2 or other tellurium oxides, requiring handling in a glovebox or inert atmosphere. All samples are shipped in microtorr-pressure boxes back-filled with argon for safe transport.
