• , valleytronics, and nonlinear optics [2][3][4][5][6][7][8]. Many interesting phenomena can be observed, mainly due to the presence of structural irregularities such as point defects, edges, boundaries, and the formation of contaminants in the process of 2D-TMDC growth [9][10][11][12][13]. These structural

Important quantities for spintronics and valleytronics are spin (SPC) or orbital (OPC) polarizations of conductance directly expressed through partial conductances, Spin and orbital magnetic moments are

In summary, the field of photonics is ever growing and the life of people will be greatly influenced by the

Results: Here, we propose a TMDC–nanoantenna system that could effectively enhance and direct emission from the two valleys in TMDCs into diametrically opposite directions. By mimicking the emission from each valley of the monolayer of

In analogy to spintronics, the valley pseudospin could also be used as non-volatile information storage and processing, which is known as valleytronics
