Our manuscript describes a combination of quantum and semi-classical computational approaches to investigate the electronic and thermoelectric behavior of Germanium-based (Ge₂AB (A/B=S, Se, Te)) Janus monolayers. Due to the broken inversion symmetry (compared to the trivial transition metal dichalcogenides), the investigated monolayers comprise unique E-k dispersion and phonon transport characteristics. These characteristics significantly enhance the thermoelectric performance by promoting multi-valleys and staggered band effects in the E-k dispersion and coupling acoustic and optical phonons in the phonon spectra. Our findings demonstrate the potential of Ge₂AB (A/B=S, Se, Te) monolayers in highly efficient energy harvesting technologies. They emphasize their potential in next-generation thermoelectric devices, which significantly affect energy conversion technologies.
