Name: Hydrothermal Tellurene
SKU: ACMA00022944
Rating: 5 (1 reviews)

Description

Description Layered tellurene crystals were synthesized by a hydrothermal synthesis method to provide an easier way to produce thin tellurium flakes. Different from the bulk tellurene material, the tellurene synthesized at low temperature is in the shape of a thin ribbon, which is easier to peel off.

Features And Benefits

Features And Benefits Layered tellurium (Te) has a triangular lattice in which individual helical chains of Te atoms are stacked together by van der Waals-type bonds and helical around axes parallel to the [0001] direction at the centers and corners of the hexagonal unit cell. Tellurene exhibits tunable band gaps from almost direct 0.31 eV (bulk) to indirect 1.17 eV (2L) and direct 1.3 eV (1L). It has been shown to exhibit metallic behavior under certain conditions and even host DCW.

Application

Application New 2D semiconductors, topological insulators, and superconductors have numerous applications in advanced technologies, and Alfa Chemistry engineers can guide customers in material characterization and selection.
