introduction/brief CV

Welcome to my website. I hope that you to find some thing usefull.

areas of expertise

I got my PhD degree in “Instabilities of Semiconductor Lasers” from Wales University (Cardiff), UK. my research expertise and interests include the fabrication and characterization of photonics devices including LEDs, LASERs, and Solar Cells. I work on the physical properties of new photovoltaic and lasing materials.

The spin-polarized computations on the mechanical, structural, electronic, magnetic, transport and optical traits of A2BMoI6 (A = K/Rb; B = Rb/Li) double perovskites for sustainable energy applications

In this paper, we have used the spin-polarized computations to evaluate the physical properties of A2BMoI6 (A=K/Rb; B= Rb/Li). Minimum ground state energy for both compounds is attained via volume…
