In recent years, the construction of lateral heterostructures of two-dimensional (2D) monolayers of transition metal dichalcogenides (TMDC) has been attracting considerable interest due to its numerous applications in electronic and optoelectronic devices. In this work, the optical absorption coefficient of the Lateral Single Quantum Well (LSQW) based on 
is analyzed theoretically. For this purpose, we rederive the absorption coefficient equation for LSQW and investigate the parameters affecting the absorption coefficient of LSQW such as the type of polarization and incident angle as well as spin–orbit coupling (SOC). Our results show the significant effect of the spin–orbit effect on the maximum value of the absorption coefficient so that by including the SOC, the values of absorption coefficient increases. We surprisingly found that increasing the well width enhances the optical absorption in LSQW. Our findings and predictions might be implemented in new emerged optovalleytronic devices.
The original online version of this article was revised: The name of the second author M. S. Akhoundi Khezrabad was incorrectly written as M. S. Akhoundi. The name of the fourth author S. A. Hashemizadeh-Aghda was incorrectly written as S. A. S. A. Hashemizadeh-agda. The first affiliation was incorrectly given as Payame Noor University Eastern Tehran Branch, Tehran, Iran but should have been Department of Physics, Payame Noor University (PNU), Tehran, Iran.
