AI Article Synopsis
- Two-dimensional van der Waals materials, like MoS and reduced graphene oxide (rGO), have unique in-plane anisotropy, which boosts their use in thermoelectric applications.
- These materials were synthesized on a SiO/Si substrate using atmospheric chemical vapor deposition to evaluate their thermoelectric performance, confirming their structure and composition through vibrational analysis and x-ray photoelectron spectroscopy.
- The combination of continuous grains and reduced phonon lifetime improves electrical properties, leading MoS/rGO to achieve a remarkable thermoelectric figure of merit of 22,622 S/m at 315 K.
Article Abstract
Two-dimensional (2D) van der Waals materials in-plane anisotropy, caused by a low-symmetric lattice structure, has considerably increased their applications, particularly in thermoelectric. MoSand MoS/reduced graphene oxide (rGO) thin films were grown on SiO/Si substrate by atmospheric chemical vapor deposition technique to study the thermoelectric performance. Few layered MoSwas confirmed by the vibrational analysis and the composition elements are confirmed by the x-ray photoelectron spectroscopy technique. The continuous grains lead to reduced phonon life time in Aand low activation energy assists to enhance the electrical property. The MoS/rGO has achieved the highestof 22 622 S mat 315 K due to an electron-rich cloud around the electrons in S atoms near the adjacent layer of rGO.
