1. Researchers from Germany, Italy, and the UK have developed a new thermoelectric material made from germanium and tin, which can convert waste heat from processors into electricity. 2. The new semiconductor alloy, compatible with the CMOS process in chip manufacturing, is based on Group IV elements from the periodic table. 3. The integration of this material into silicon-based microchips could significantly reduce the need for external cooling and power, enhancing the efficiency of electronic devices.
