Thermal Conductivity Measurements in 2D Materials

Abstract

Measuring the thermal conductivity of materials is a very important field as the continuation of the improvement in modern electronics and optoelectronics heavily depends on the thermal management. Both high thermal conductivity and low thermal conductivity materials are required in the device design. Besides the fields mentioned above, excess heat scavenging via thermoelectric devices is an ever-growing field. Thermoelectric devices performance is determined by the figure of merit \(Z=S^2 \sigma \kappa \) where S is the Seebeck coefficient, \(\sigma \) is the electrical conductivity and \(\kappa \) is the thermal conductivity. Materials that are good electrical conductors and thermal insulators are needed for efficient thermoelectric devices.
