Abstract

The goal of my research was to mechanically exfoliate single to few atomic layer samples of Molybdenum Disulfide (MoS₂ ), Tungsten Diselenide (WSe₂ ), and Tungsten Disulfide (WS₂ ) and characterize these 2D materials by multiple methods. I used Atomic Force Microscopy, Raman Spectroscopy, and Optical Microscopy to accomplish this. In addition, I measured the electrical properties of the exfoliated materials by fabricating a device and taking basic measurements.
