| Research Abstract |
Optical spectroscopic measurements provided us with information about lattice vibrations and electronic states of single and few-layer layered semiconductors. This information revealed competitive relationship between interlayer interaction and dielectric interaction and the effect of the interlayer interaction on the electronic states, which contributes to the development of fundamental research area directly connected to nano-electronics.
Field effect transistors (FETs) consisting of single layer MoS2 were successfully fabricated and the mobility of the FETs was at world highest level as a back-gate MoS2-FET. It is therefore considered that we will be able to find a layered semiconductor superior to graphene as an electronic material if we continue our study.
