From: Strain Effect on Thermoelectric Performance of InSe Monolayer
The contribution of ZA, TA, LA, and optical modes to the group velocity of monolayer InSe for (a) unstrained and (b) 6% strained systems. c Phonon heat capacity (Cph) and Gruneisen parameter as a function of strain at 300 K. d Phonon scattering rate of unstrained and 6% strained monolayer InSe as a function of frequency.
