Hot-electron cooling by acoustic and optical phonons in monolayers of MoS${}_2$ and other transition-metal dichalcogenides

Kristen Kaasbjerg, K. S. Bhargavi, S. S. Kubakaddi

We study hot-electron cooling by acoustic and optical phonons in monolayer MoS${}_2$. The cooling power $P$ ($P_e=P/n$) is investigated as a function of electron temperature $T_e$…
