Inelastic Neutron Scattering Study of Thermoelectric Material ?-InSe

Abstract: Two dimensional (2D) metal chalcogenides are constituted by covalently/ionically bonded atomic layers that are held together via interlayer van der Waals (vdW) forces. In ambient conditions, InSe crystals usually possess three polytype layered structures, i.e., two hexagonal phases of ?-type and ?-type and one rhombohedral phase of ?-type. the ionic In-Se bond, the covalent In-In bond, and interlayer vdW interactions. The atomic vibration/bonding characters and the microscopic physical properties can be bridged by the dispersion properties of phonons. In this continued proposal, we want to use time of flight technique to obtain the phonon dispersion spectra of ?-InSe. Combining first-principle calculation, we could explain and regulate the thermal, thermoelastic and transport properties of InSe.
