Bismuth telluride is widely used in thermoelectric devices due to its excellent thermoelectric properties at room temperature. It is commonly employed in thermoelectric coolers and power generators, where it efficiently converts temperature differences into electrical voltage and vice versa. This makes it valuable in applications such as cooling electronic components, including CPUs and laser diodes, to maintain optimal operating temperatures. Additionally, it is used in waste heat recovery systems to generate electricity from industrial processes, enhancing energy efficiency. Its stability and performance in near-room-temperature environments make it a preferred material in both consumer electronics and industrial applications.
