High Chern numbers in a perovskite-derived dice lattice (LaO)/(LaAlO)(111) with Ti, Mn and Co
Okan Köksal, L. L. Li, Rossitza Pentcheva
The dice lattice, containing a stack of three triangular lattices, has been proposed to exhibit nontrivial flat bands with nonzero Chern numbers, but unlike the honeycomb lattice i…
Concomitant appearance of conductivity and superconductivity in (111)LaAlO3/SrTiO3 interface with metal capping
R. S. Bisht, M. Mograbi, P. K. Rout +7
In polar-oxide interfaces, a certain number of monolayers (ML) is needed for conductivity to appear. This threshold for conductivity is explained by accumulating sufficient electri…
Exciton states in a circular graphene quantum dot: magnetic field induced intravalley to intervalley transition
L. L. Li, M. Zarenia, W. Xu +2
The magnetic-field dependence of the energy spectrum, wave function, binding energy and oscillator strength of exciton states confined in a circular graphene quantum dot (CGQD) are…
Electric- and magnetic-field dependence of the electronic and optical properties of phosphorene quantum dots
L. L. Li, D. Moldovan, W. Xu +1
Recently, black phosphorus quantum dots were fabricated experimentally. Motivated by these experiments, we theoretically investigate the electronic and optical properties of rectan…
Polarization-driven topological insulator transition in a GaN/InN/GaN quantum well
M. S. Miao, Q. Yan, C. G. Van de Walle +3
Topological insulator (TI) states have been demonstrated in materials with narrow gap and large spin-orbit interactions (SOI). Here we demonstrate that nanoscale engineering can al…
