A thermoelectric alloy achieves high performance in electronic cooling Thermoelectrics is a green-energy technology that can use charge carrier transport within a material to achieve mutual conversion between thermal and electrical energy, consequently enabling both power generation and electronic cooling (1). It is relevant to various advanced technologies such as wireless communications, microelectronics, and medicine because thermoelectric (TE) devices have high mechanical reliability, can rapidly respond, and can vary in size and structure, depending on the application. On page 841 of this issue, Liu et al. (2) describe how tin selenide (SnSe) crystals can be improved as a TE material at room temperature by innovatively plaining the crystal lattice. The ground-breaking strategy produces a game-changer in seriously underdeveloped economical, eco-friendly, and noiseless cooling markets.
