EuCdAs: a magnetic semiconductor
D. Santos-Cottin, I. Mohelský, J. Wyzula +18
EuCdAs is now widely accepted as a topological semimetal in which a Weyl phase is induced by an external magnetic field. We challenge this view through firm experimental ev…
Engineering axion insulator phase in superlattices with inversion symmetry breaking
Rajibul Islam, Sougata Mardanya, Alexander Lau +6
We study theoretically the interplay between magnetism and topology in three-dimensional HgTe/MnTe superlattices stacked along the (001) axis. Our results show the evolution of the…
Electronic and optical properties of InAs/InAsSb superlattices and their application to far-infrared detectors
Ghulam Hussain, Giuseppe Cuono, Rajibul Islam +4
We calculate the electronic and optical properties of InAs/InAsSb superlattices within relativistic density functional theory. To have a good description of the…
Topological states in superlattices of HgTe-class materials for engineering three-dimensional flat bands
Rajibul Islam, Barun Ghosh, Giuseppe Cuono +7
In search of materials with three-dimensional flat band dispersions, using {\em ab-initio} computations, we investigate how topological phases evolve as a function of hydrostatic p…
From narrow-gap and semimagnetic semiconductors to spintronics and topological matter: a life with spins
Tomasz Dietl
The abundance of semiconductors in our smartphones, computers, fiber optic junctions, cars, light sources, photovoltaic and thermoelectric cells results from the possibilities of c…
Momentum-resolved spin splitting in Mn-doped trivial CdTe and topological HgTe semiconductors
Carmine Autieri, Cezary Śliwa, Rajibul Islam +2
Exchange coupling between localized spins and band or topological states accounts for giant magnetotransport and magnetooptical effects as well as determines spin-spin interactions…
