Reconfiguring Lone-Pair Electrons for High-Performance n-Type SnSe Thermoelectrics
Direct conversion of abundant waste heat into electricity offers a promising route to more efficient energy use, motivating the development of thermoelectric materials with high figure of merit (ZT). In SnSe, Sn 5s2 LPEs are widely recognized as the origin of ultralow lattice thermal conductivity. However, their role...
