High thermoelectric performance realized through manipulating layered phonon-electron decoupling

High thermoelectric performance realized through manipulating layered phonon-electron decoupling Thermoelectric materials allow for direct conversion between heat and electricity, offering the potential for power generation. The average dimensionless figure of merit ZT ave determines device efficiency. N-type tin selenide crystals exhibit outstanding three-dimensional charge and two-dimensional phonon transport along the out-of-plane direction, contributing to a high maximum figure of merit Z m...
