"naturally found in deep hydrothermal gold and quartz deposits... scientists grew it to 100 nm thin employing molecular beam epitaxy, minimizing defects in its crystalline structure... tetradymites cause cooling effect in commercial thermoelectric coolers... uses far less power than conventional silicon-based spintronics... topological insulator... material's electrical resistance oscillates, meaning very high electron mobility: 10,000 cm2/V-s... spintronics, wearable thermoelectric devices"
