Preparation and characterization of few layered mos2 nano flakes

Abstract

Two dimensional layered materials have become a prominent area of current research and development due to the significant properties exhibited by them. Exploiting graphene's layered structure have led to the property enhancement and thereby making it a good candidate for potential applications. MoS2 (Molybdenum disulphide), a transition metal dichalcogenide possess exceptional electrical, thermal and mechanical properties which can be well exploited on exfoliation. The present work report the exfoliation of pristine MoS2. The layers of pristine MoS2 are held together by weak van der Waals interaction, which is disturbed by the addition of a suitable modifier facilitating the exfoliation process. The modifier treated MoS2 is elucidated by powder X-ray diffraction, Photoluminesence and Raman spectroscopy.
