Polymorphic nanowires of magnetic shape memory MnAs
C. Echeverría-Arrondo, J. Pérez-Conde, A. Ayuela
For nanostructured materials, strain is of fundamental importance in stabilizing a specific crystallographic phase, modifying electronic properties, and in consequence their magnet…
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…
Acceptor and donor impurities in GaN nanocrystals
C. Echeverría-Arrondo, J. Pérez-Conde, A. K. Bhattacharjee
We investigate acceptor and donor states in GaN nanocrystals doped with a single substitutional impurity. Quantum dots (QD's) of zinc-blende structure and spherical shape are consi…
