【Abstract】 Thermoelectric materials are the functional materials that can convert heat energy to electric energy or vise versa directly using thermoelectric effects and have immense application prospects in thermoelectric power generation and refrigeration. SiGe alloy is one kind of up-and-coming thermoelectric material that is usually used in high-temperature field.This paper discusses the thermoelectric properties and fabrication means,and also reviews the ways of how to improve thermoelectric performances.更多还原
