Open AccessA record thermoelectric efficiency in tellurium-free modules for low-grade waste heat recovery
Low-grade heat accounts for >50% of the total dissipated heat sources in industries. An efficient recovery of low-grade heat into useful electricity not only reduces the consumption of fossil-fuels but also re...

Open AccessLeveraging bipolar effect to enhance transverse thermoelectricity in semimetal Mg2Pb for cryogenic heat pum**
Toward high-performance thermoelectric energy conversion, the electrons and holes must work jointly like two wheels of a cart: if not longitudinally, then transversely. The bipolar effect — the main performanc...

Open AccessVacancy-induced dislocations within grains for high-performance PbSe thermoelectrics
To minimize the lattice thermal conductivity in thermoelectrics, strategies typically focus on the scattering of low-frequency phonons by interfaces and high-frequency phonons by point defects. In addition, sc...

Open AccessTellurium as a high-performance elemental thermoelectric
High-efficiency thermoelectric materials require a high conductivity. It is known that a large number of degenerate band valleys offers many conducting channels for improving the conductivity without detriment...

Convergence of electronic bands for high performance bulk thermoelectrics
The use of thermoelectric devices to convert waste heat into electricity is anticipated to find many applications, but most thermoelectric materials are relatively inefficient. Attempts are being made to impro...
