“…Therefore, these materials are very useful in the development of thin-film solar cells, radiation detectors, photocatalysts, various optoelectronic devices, photoresistors, LEDs, and phosphors [ 2 , 3 , 4 , 5 , 6 , 7 ]. However, it turned out that II–VI semiconductor compounds, in addition to having excellent luminescent and photoelectric properties, also have interesting surface properties important for gas sensor applications [ 8 , 9 ]. Some parameters of compounds II–VI, important for applications, are given in Table 1 .…”

A review of the state of research in the development of conductometric gas sensors based on II–VI semiconductors is given. It was shown that II–VI compounds indeed have properties that are necessary for the development of highly efficient gas sensors. In this case, to achieve the required parameters, all approaches developed for metal oxides can be used. At the same time, during a detailed review, it was concluded that sensors based on II–VI compounds have no prospects for appearing on the gas sensor market. The main obstacle is the instability of the surface state, which leads to poor reproducibility of parameters and drift of sensor characteristics during operation.

“…It has been established that, despite high melting temperatures (see Table 1 ), the stoichiometry and phase composition of the surface of these semiconductors are strongly influenced by temperature and environmental conditions [ 8 , 118 , 119 , 120 ]. For example, at normal pressure, the most stable compound, ZnS, does not melt.…”

A change in the composition and dopant content of selective atoms in a material leads to their new desired properties by altering the structure, which can significantly improve the performance of relevant devices. By acknowledging this, we focused on characterizing the optoelectronic and structural properties of cadmium-substituted zinc selenide (Zn1-xCdxSe; 0 ≤ X ≤ 1) semiconductors using density functional theory (DFT) within the generalized gradient approximation (GGA), EV-GGA, and mBJ approximations. The results proved the cubic symmetry of the investigated materials at all Cd concentrations (0, 0.25, 0.50, 0.75, and 1). Although a linear surge in the lattice constant is observed with the change in Cd content, the bulk modulus exhibits a reverse trend. These materials are observed to be direct bandgap semiconductors at all Cd concentrations, with a decrease in electronic bandgap from 2.76 eV to 1.87 eV, and have isotropic optical properties, showing their potential applicability as a blue-to-red display. The fundamental optical properties of the materials, such as optical conductivity, reflectance, refractive index, absorption, and extinction coefficient, are also discussed. These outcomes provide a computational understanding of the diverse applications of Zn1-xCdxSe semiconductors in optoelectronic, photonic, and photovoltaic devices, particularly for a visible-range display.
