A thin film efficient pn-junction thermoelectric device fabricated by self-align shadow mask.

ABSTRACT: Large area highly crystalline MoS₂ and WS₂ thin films were successfully grown on different substrates using radio-frequency magnetron sputtering technique. Structural, morphological and thermoelectric transport properties of MoS_2, and WS₂ thin films have been investigated systematically to fabricate high-efficient thermal energy harvesting devices. X-ray diffraction data revealed that crystallites of MoS₂ and WS₂ films are highly oriented in 002 plane with uniform grain size distribution confirmed through atomic force microscopy study. Surface roughness increases with substrate temperature and it plays a big role in electron and phonon scattering. Interestingly, MoS₂ films also display low thermal conductivity at
