Effect of gallium doping on structural and transport properties of the topological insulator Bi2Se3 grown by molecular beam epitaxy
Daniel Brito, Ana Pérez-Rodriguez, Ishwor Khatri +6
Topological insulators possess a non-conductive bulk and present surface states, henceforth, they are electrically conductive along their boundaries. Bismuth selenide ()…
Van Der Waals Heteroepitaxy of GaSe and InSe, Quantum Wells and Superlattices
Marcel S. Claro, Juan P. Martínez-Pastor, Alejandro Molina-Sánchez +7
Bandgap engineering and quantum confinement in semiconductor heterostructures provide the means to fine-tune material response to electromagnetic fields and light in a wide range o…
Ising and XY paramagnons in two-dimensional 2H-NbSe
A. T. Costa, M. Costa, J. Fernández-Rossier
Paramagnons are the collective modes that govern the spin response of nearly magnetic conductors. In some cases they mediate electron pairing leading to superconductivity. This sce…
Wafer-scale fabrication of two-dimensional beta-In2Se3 photodetectors
Marcel S. Claro, Justyna Grzonka, Nicoleta Nicoara +2
The epitaxial growth of two-dimensional (2D) material was obtained over 2-inches c-sapphire wafers using molecular beam epitaxy (MBE). Excellent quality of thick (90 n…
Monolayer transition metal dichalcogenides in strong magnetic fields: Validating the Wannier model using a microscopic calculation
J. Have, G. Catarina, T. G. Pedersen +1
Using an equation of motion (EOM) approach, we calculate excitonic properties of monolayer transition metal dichalcogenides (TMDs) perturbed by an external magnetic field. We compa…
Anomalous magnetism in hydrogenated graphene
N. A. García-Martínez, J. L. Lado, D. Jacob +1
We revisit the problem of local moment formation in graphene due to chemisorption of individual atomic hydrogen or other analogous sp covalent functionalizations. We describe g…
