Method of Creating Micro-Scale Silver Teiluride Grains Covered with Bismuth Nanoparticles

摘要

NASA Langley Research Center has developed a novel thermoelectric (TE) material utilizing micro-scale silver teiluride grains covered with bismuth nanoparticles. These materials have unique advantages in directly converting any level of thermal energy into electrical power and solid-state cooling by a reverse mode. Although thermo-electric devices are regarded advantageously with their high reliability, their lack of moving parts, and their ability to scale to any sizes, the devices' energy conversion efficiency remains generally poor.
