Investigation of optical properties of penta-boron carbide two-dimensional nanostructure by density function theory with applied approach in defense industry

In this paper, the optical properties of penta-boron carbide two-dimensional nanostructure (B2C) have been studied using simulations with computational codes based on density function theory based on initial calculations. The study of electronic properties shows that this two-dimensional nanostructure is an indirect semiconductor with an energy gap of 1.49 electron volts by the PBE approximation method. Study of optical properties of this nanostructure by PBE-GGA approximation method In addition to showing the agreement of optical aspects with the electronic properties of this two-dimensional monolayer, this nanostructure can in the future, as a suitable material in the design of electro-optical devices in industry Different to be used. According to the findings of this study based on the relatively high absorption rate and very low reflectivity of this nanomaterial in the visible spectrum, this nanostructure can be used for optical applications, especially in the design of solar energy devices and optical sensors with various applications in the defense industry.
