The College of Education for Pure Sciences at the University of Basrah  discussed a master’s thesis in a theoretical study of electronic, magnetic and optical properties during biaxial stress and electric field in the case of the monolayer CrTe.
The letter presented by the researcher (Ali Abdul-Hussein Nasser) included
On the basis of first-principles calculations, we explained in this study the two-dimensional layers of ferromagnetic materials for CrTe. We also examined the effects of electric field and biaxial stress on the properties of single-layer CrTe to determine its electronic, magnetic, structural and optical properties. Where the monolayer CrTe shows semi-metallic properties indicating that the spin channel upstream is metallic and the downward spin channel is semiconductor with an energy gap of 0.741 eV. The magnetic moment per unit cell of CrTe is 4μB. The CrTe complex maintains the semi-metallic property in all cases of biaxial stress. Moreover, the value of the energy gap of the twisting electrons decreases with tensile stress and increases with compressive stress under the influence of biaxial stress. The electric field significantly affects the energy gap but the semimetallic feature is destroyed when the electric field value is 0.9V/nm. Distinctive optical properties determine that monolayer CrTe is a strong competitor for use in microelectronic and optoelectronic device applications.
