“…Semiconductors have high absorption coefficients for short wavelengths (high energy and frequency spectrum) and low absorption coefficients for long wavelengths (they do not have enough energy to excite electrons from the valence band to the conduction band). MoS 2 has a relatively large absorption coefficient for the wavelengths from 400 nm to 500 nm with a sharp decay at 500 nm [45]. The key factor behind the wide use of MoS 2 in optoelectronics is its tunable bandgap that changes with size and structure; Different bandgaps mean tunable photoresponsivity (R), specific detectivity, and response time [46], and thus, a wide range of applications.…”

“…The absorption coefficient of MoS 2 was influenced by various factors, such as the chemical composition of the material, its thickness, and the wavelength of light being used. In the case of MoS 2 , its absorption coefficient is relatively large for wavelengths ranging from 400 nm to 500 nm [ 66 ]. The bandgap of bulk MoS 2 changes when it is reduced to a few layers.…”
