A thermoelectric figure of merit that is unprecedentedly high has been observed in SnSe crystals. This finding suggests that bulk materials with a layered structure and highly anharmonic lattice vibrations can feature an intrinsically low thermal conductivity and high thermoelectric efficiency. Together with other recent findings in this field, it urges us to revisit basic design principles for thermoelectric materials.
