A reduction in the electronic-dimensionality of materials is one method for achieving improvements material properties. Here, a demonstrated using simple hydrogen treatment technique. Quantum well states from hydrogen-treated bulk 2H-MoS2 are observed angle resolved photoemission spectroscopy (ARPES). The electronic confined within few MoS2 layers after treatment. significant band-gap can also be achieved treatment, and both phenomena explained by formation sulfur vacancies generated chemical reaction between hydrogen.
