The College of Education for Pure Sciences organized a scientific lecture on (theoretical investigation of electronic and magnetic properties and properties).
Optical cross biaxial stress and electric field
of the CrTe monolayer using first-principles calculations.
The lecture presented by the student (Ali Abdul-Hussein Nasser) included that we found that the semi-metallic property exists for the monolayer of CrTe and that the magnetic moment is equal to (4µB) for each unit cell. Under the influence of biaxial stress, the size of the energy gap in the spin channel decreases under tensile stress and increases under compressive stress. The magnetic moment values ​​do not show any change, thus, the behavior of HM can be maintained at high stress values. The semimetallic property will be destroyed when an electric field is applied (E = 0.9V/nm), as (Cr) has a great effect in achieving the semimetallic property before the effect of this electric field. By studying the optical properties of this compound, it was found that this compound is a good candidate in applications related to microelectronics and optoelectronics.
