Monolayer materials typically display intriguing temperature-dependent dielectric and optical properties, which are crucial for improving the structure and functionality of associated devices. Due to its unique photoelectric capabilities, monolayer WSe2 has recently received a lot of attention in the fields of atomically thin electronics and optoelectronics. In this work, we focus on the evolution of the temperature-dependent dielectric and optical properties of 2D WSe2 over energies from 0.74 to 6.40 eV and temperatures from 40 K to 350 K. We analyze second derivatives with respect to energy to locate the critical points (CP). The dependence of the observed CP energies on temperature is consistent with the alternative domination of the declining exciton binding energy as the temperature increases.

“…Additionally, low‐cost materials with a small band gap are necessary for optoelectronics. Other conventional narrow band gap semiconductors might not be as effective as the class of narrow band gap ternary compounds [9]. These barium‐based chalcogenides exhibit certain structural similarities isotypic to Ba 2 MnX 3 (X = S, Se, Te), which is likewise isotypic to K 2 AgI 3 [10].…”

Ternary chalcogenides with direct band gaps are remarkable for being used in many optoelectronic applications. We investigated for structural, electronic, optical, and transport characteristics of new Ba2CdCh3 (Ch = S, Se, Te) semiconductors using the full‐potential linearized augmented plane wave (FP‐LAPW) approach. The band structures of these compounds confirm a direct type of band gap. The phonon dispersion plots along with the predicted negative formation energies suggest these compounds to be thermodynamically stable. Additionally, important optical characteristics were computed and thoroughly explained. The different ELF spectra were calculated in which strong peak correlate precisely with plasma resonance. Moreover, we also explored the thermodynamic characteristics of the ternary systems by employing the quasi‐harmonic Debye model. These compounds were also suitable for thermoelectric applications based on the detailed discussion of the computed significant thermoelectric properties. In general, the advancement of various and promising semiconducting devices and their applications will be supported by the present study.
