  We report on the temperature dependence of in-plane E2g and out of plane A1g
Raman modes in high quality few layers MoS2 (FLMS) prepared using a high
temperature vapor-phase method. The materials obtained were investigated using
transmission electron microscopy. The frequencies of these two phonon modes
were found to vary linearly with temperature. The first order temperature
coefficients for E2g and A1g modes were found to be 1.32*10-2 and 1.23*10-2
cm-1/K, respectively. The thermal conductivity of the suspended FLMS at room
temperature was estimated to be about 52 W/mK.
