Strain effects in the absorption coefficient and relative refractive index change in double asymmetric Al Ga1−N/GaN quantum wells

Autor: F.M. Nava-Maldonado, M.E. Mora-Ramos, J.G. Rojas-Briseño, J.C. Martínez-Orozco

Publikováno v: Physica E: Low-dimensional Systems and Nanostructures. 111:134-140

We theoretically investigate the optical absorption and the relative change in the index of refraction in asymmetric double zinc-blende Al xGa1−x N/GaN quantum wells . Particular emphasis is put in revealing the influence of lattice strain on these

Tunneling magnetoresistance and spin-valley polarization in magnetic silicene superlattices

Autor: J.G. Rojas-Briseño, P. Villasana-Mercado, Isaac Rodríguez-Vargas, M. A. Flores-Carranza, S. Molina-Valdovinos

Publikováno v: Physical Review B. 103

We study the tunneling magnetoresistance and the spin-valley transport in silicene-based magnetic superlattices. The superlattice profile is obtained by the periodic modulation of the exchange field induced by ferromagnetic electrodes. The silicene b

States of direct and indirect excitons in strained zinc-blende GaN/InGaN asymmetric quantum wells

Autor: M.E. Mora-Ramos, J.C. Martínez-Orozco, J.G. Rojas-Briseño

Publikováno v: Superlattices and Microstructures. 112:574-583

The total and binding energies of excitons in step-like asymmetric quantum wells made of zincblende GaN/InxlGa(1−xl)N/InxrGa(1−xr)N/GaN are theoretically reported. It is discussed how the asymmetry in the carrier confinement leads to singular beh

Heavy and light exciton states in c-AlGaN/GaN asymmetric double quantum wells

Autor: J.G. Rojas-Briseño, M.E. Mora-Ramos, J.C. Martínez-Orozco, Isaac Rodríguez-Vargas

Publikováno v: Physica E: Low-dimensional Systems and Nanostructures. 124:114248

This work presents a theoretical study of the lowest heavy- and light-exciton energy states in a c-AlGaN/GaN asymmetric double quantum well. It makes use of the variational method to determine the eigenstates of the corresponding Schrodinger equation
