Thermal Expansion Coefficient of Monolayer Molybdenum Disulfide Using Micro-Raman Spectroscopy by Zhang, Lenan, Lu, Zhengmao, Song, Youngsup, Zhao, Lin, Bhatia, Bikram, Bagnall, Kevin R, Wang, Evelyn N

“…In this work, we present a three-substrate approach to characterize the TEC of monolayer molybdenum disulfide (MoS2) using micro-Raman spectroscopy. The temperature dependence of the Raman peak shift was characterized with three different substrate conditions, from which the in-plane TEC of monolayer MoS2 was extracted on the basis of lattice symmetries. …”
