Quantum engineering of GaAs nanoribbons for advanced thermoelectric energy conversion
Abstract
reaches 0.85, which is 37% better than performance at room temperature. The model identifies distinct operational regimes: cryogenic temperatures (100-200 K) maximize Seebeck coefficients for cooling applications, while elevated temperatures (400-550 K) optimize power generation efficiency through the optimal trade-off between preserved quantum confinement effects and thermally enhanced electrical conductivity. This integrated first-principles and machine learning framework provides comprehensive insights into temperature-dependent transport phenomena and establishes GaAs nanoribbons as promising candidates for next-generation thermoelectric devices across a broad operational spectrum.
