Electrochemical exfoliation of transition metal dichalcogenides for improved photodetection

Transition metal dichalcogenides, such as molybdenum disulfide, can be thinned down from bulk crystals into few or single atomic layers that exhibit unique optoelectronic properties due to quantum confinement. The proposed work aims to exfoliate these materials into single to few layers using a new electrochemical exfoliation technique and to study their optoelectronic properties when deposited as single layers using a technique where these materials are floated on water to create large area films. Their response to light will be evaluated to determine their effectiveness as potential device candidates and bottlenecks to electron/hole transport will be determined using various state-of-the-art characterization facilities.
