Abstract

We report the in-plane thermal conductivity of suspended exfoliated few-layer molybdenum disulfide (MoS2) samples that were measured by suspended micro-devices with integrated resistance thermometers. The obtained room-temperature thermal conductivity values are (44-50) and (48-52) W m -1 K-1 for two samples that are 4 and 7 layers thick, respectively. For both samples, the peak thermal conductivity occurs at a temperature close to 120 K, above which the thermal conductivity is dominated by intrinsic phonon-phonon scattering although phonon scattering by surface disorders can still play an important role in these samples especially at low temperatures. © 2014 AIP Publishing LLC.
