Electron Confinement Induced by Diluted Hydrogen-like Ad-atoms in Graphene Ribbons
J. W. González, L. Rosales, M. Pacheco +1
We report the electronic properties of two-dimensional systems made of graphene nanoribbons which are patterned with ad-atoms in two separated regions. Due to the extra electronic…
Van der Waals interaction in magnetic bilayer graphene nanoribbons
H. Santos, A. Ayuela, L. Chico +1
We study the interaction energy between two graphene nanoribbons by first principles calculations, including van der Waals interactions and spin polarization. For ultranarrow zigza…
Magnetism of Covalently Functionalized Carbon Nanotubes
Elton J. G. Santos, D. Sanchez-Portal, A. Ayuela
We investigate the electronic structure of carbon nanotubes functionalized by adsorbates anchored with single C-C covalent bonds. We find that, despite the particular adsorbate, a…
First-principles calculations of the magnetic properties of (Cd,Mn)Te nanocrystals
C. Echeverría-Arrondo, J. Pérez-Conde, A. Ayuela
We investigate the electronic and magnetic properties of Mn-doped CdTe nanocrystals (NCs) with 2 nm in diameter which can be experimentally synthesized with Mn atoms inside. Using…
Optical spin control in nanocrystalline magnetic nanoswitches
C. Echeverría-Arrondo, J. Pérez-Conde, A. Ayuela
We investigate the optical properties of (Cd,Mn)Te quantum dots (QDs) by looking at the excitons as a function of the Mn impurities positions and their magnetic alignments. When do…
Antiferromagnetic order in (Ga,Mn)N nanocrystals: A density functional theory study
C. Echeverría-Arrondo, J. Pérez-Conde, A. Ayuela
We investigate the electronic and magnetic properties of (Ga,Mn)N nanocrystals using the density functional theory. We study both wurtzite and zinc-blende structures doped with one…
