High and anomalous thermal conductivity in monolayer MSi${}_2$Z${}_4$ semiconductors

Yan Yin, Min Yi, Wanlin Guo

The lattice thermal conductivity ($\kappa$) of newly synthesized two-dimensional (2D) MoSi${}_2$N${}_4$ family and its associated abnormality is anatomized by $ab$ $initio$ phonon Boltzmann…
