Understanding of the mechanism driving spin-reorientation transition in the magnetic ultrathin films. Enhancement of conversion efficiency of solar cells is the way to use solar energy to produce electricity.
My research projects are in two different fields like magnetism of materials study and
semiconductors for PV application. Theoretical investigations of physical properties of materials are performed by SPR-LMTO-ASA, WIEN2K and VASP codes. For the first field, I study the structural, magnetic and magneto optical behaviors of 3d ultrathin layers on noble metals. This research is motivated by the need of high storage data technology devices. Recently, hard disk drivers are developed by means of perpendicular magneto optical recording technique. This last is emerging as a new erasable storage technology and it opens new area of optimization hard disks based on increasing of polar spin density. Over the past 20th years, magnetic multilayer’s have a panoply of practical applications. It can be used to produce devices that exploit the spin rather than the electron charge.
In the second field, I study the electronic and optical properties of semiconductors on
hetero-structure to reach a better understanding of band offset mechanism between n-type and p-type semiconductors for PV application.
