| description | This study delves into the interband absorption dynamics of polarized radiation in monatomic layers of transition metal dichalcogenides (TMDs), a field critical to advancing nano- and optoelectronics. Using theoretical modeling and computational analysis, the spectral and temperature dependencies of one- and two-photon absorption coefficients were examined for linearly and circularly polarized light. Results reveal a pronounced increase in absorption coefficients with frequency, reaching a peak before declining, a behavior modulated by the material's bandgap and temperature. The analysis further highlights the substantial impact of light polarization on absorption characteristics, with temperature-dependent shifts in the maximum absorption frequency. These findings contribute to a deeper understanding of the optical properties of 2D TMD materials and pave the way for their application in designing efficient photodetectors, light-emitting diodes, and other next-generation optoelectronic devices. |
