Description

Description ReSe2 is a semiconductor (~1.1 eV). The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers. Rhenium diselenide is a Group VII transition metal dichalcogenide (TMDC).

Features And Benefits

Features And Benefits The ReSe2 crystals we produce have a triangular shape and metallic appearance. We produce n-type ReSe2 with a typical charge carrier density of about 1016 cm-3 at room temperature.

Application

Application Due to its reduced lattice symmetry, it also has potential applications in electronics, optoelectronics and thermoelectrics such as photodetectors, lasers and transistors.
ReSe2 has also a wide range of applications including strain sensors, stretchable electrodes, and flexible FETs, solar cells, and other photonic devices.
