This thesis specializes in the research of the optical reaction of latest atomically skinny two-dimensional crystals, mostly the kinfolk of transition steel dichalcogenides like MoS2. One significant subject of the thesis is the fitting therapy of the linear and second-order nonlinear optical susceptibilities of atomically skinny transition steel dichalcogenides. as well as their major clinical curiosity as primary fabric responses, those reports supply crucial wisdom and handy characterization instruments for the applying of those 2nd fabrics in opto-electronic units. one other very important subject of the thesis is the valley physics of atomically skinny transition steel dichalcogenides. it really is proven that the degeneracy within the valley measure of freedom could be lifted and a valley polarization could be created utilizing a magnetic box, which breaks time reversal symmetry in those fabrics. those findings increase our simple realizing of the valley digital states and open up new possibilities for valleytronic purposes utilizing two-dimensional materials.
