Precise tuning of the Curie temperature of (Ga,Mn)As-based magnetic semiconductors by hole compensation: Support for valence-band ferromagnetism
Shengqiang Zhou, Lin Li, Ye Yuan +11
For the prototype diluted ferromagnetic semiconductor (Ga,Mn)As, there is a fundamental concern about the electronic states near the Fermi level, i.e., whether the Fermi level resi…
Polaron effects on the dc- and ac-tunneling characteristics of molecular Josephson junctions
B. H. Wu, J. C. Cao, C. Timm
We study the interplay of polaronic effect and superconductivity in transport through molecular Josephson junctions. The tunneling rates of electrons are dominated by vibronic repl…
Application of a time-convolutionless stochastic Schrödinger equation to energy transport and thermal relaxation
Robert Biele, Carsten Timm, Roberto D'Agosta
Quantum stochastic methods based on effective wave functions form a framework for investigating the generally non-Markovian dynamics of a quantum-mechanical system coupled to a bat…
Tailoring the magnetism of GaMnAs films by ion irradiation
Lin Li, S. D. Yao, Shengqiang Zhou +10
Ion irradiation of semiconductors is a well understood method to tune the carrier concentration in a controlled manner. We show that the ferromagnetism in GaMnAs films, known to be…
Theory for Magnetism and Triplet Superconductivity in LiFeAs
P. M. R. Brydon, M. Daghofer, C. Timm +1
Superconducting pnictides are widely found to feature spin-singlet pairing in the vicinity of an antiferromagnetic phase, for which nesting between electron and hole Fermi surfaces…
Correlated defects, metal-insulator transition, and magnetic order in ferromagnetic semiconductors
C. Timm, F. Schäfer, F. von Oppen
The effect of disorder on transport and magnetization in ferromagnetic III-V semiconductors, in particular (Ga,Mn)As, is studied theoretically. We show that Coulomb-induced correla…
