Unveiling the Role of Electronic, Vibrational, and Optical Features of the 1T' WSe Monolayer.

Understanding the optoelectronic profile and chemical stability of transition-metal dichalcogenides (TMDs) is crucial for advancing two-dimensional (2D) material applications, particularly in electronics, optoelectronics, and energy devices. Here, we investigate the structural, electronic, optical, and excitonic properties of the 1T' WSe monolayer. Phonon dispersion analysis confirmed the thermodynamic stability of this system.
