Large Magnetoresistance in Co/Ni/Co Ferromagnetic Single Electron Transistors
R. S. Liu, H. Pettersson, L. Michalak +3
We report on magnetotransport investigations of nano-scaled ferromagnetic Co/Ni/Co single electron transistors. As a result of reduced size, the devices exhibit single electron tra…
Managing the supercell approximation for charged defects in semiconductors: finite size scaling, charge correction factors, the bandgap problem and the ab initio dielectric constant
C. W. M. Castleton, A. Hoglund, S. Mirbt
The errors arising in ab initio density functional theory studies of semiconductor point defects using the supercell approximation are analyzed. It is demonstrated that a) the lead…
Finite size scaling as a cure for supercell approximation errors in calculations of neutral native defects in InP
C. W. M. Castleton, S. Mirbt
The relaxed and unrelaxed formation energies of neutral antisites and interstitial defects in InP are calculated using ab initio density functional theory and simple cubic supercel…
Spin-transfer mechanism of ferromagnetism in polymerized fullerenes: calculations
O. E. Kvyatkovskii, I. B. Zakharova, A. L. Shelankov +1
A mechanism of the high temperature ferromagnetism in polymerized fullerenes is suggested. It is assumed that some of the C molecules in the crystal become magnetically acti…
Post-growth annealing of GaMnAs under As capping - an alternative way to increase Tc
M. Adell, V. Stanciu, J. Kanski +7
We demonstrate that in situ post-growth annealing of GaMnAs layers under As capping is adequate for achieving high Curie temperatures (Tc) in a similar way as ex situ annealing in…
