Abstract
In this work, we demonstrate the thinning of an exfoliated molybdenum disulfide flake by thermal oxidation as first demonstrated by Jumiati Wu et. al. Using this technique we achieve a thinning of an exfoliated flake from 7nm to 2nm. In addition, we attempt to thin a second flake synthesized by chemical vapor deposition initially 3nm thick. Unfortunately the thinning process completely destroyed the synthesized flake as shown by optical microscopy.
