"2-dimensional electron gas (2DEG) system with multiple sub-bands... facilitates better conversion from temperature (heat) to electricity and improves the mobility of electrons in their 2D sheet. This readily benefits everyday devices like semiconductors... thermoelectric conversion power factor improved 4X compared with conventional 2DEG... thin thermoelectric films on substrates made of gallium arsenide...  environmental monitoring systems in remote locations, wearable devices for medical monitoring"
