S-wave/spin-triplet order in superconductors without inversion symmetry: LiPdB and LiPtB
H. Q. Yuan, D. F. Agterberg, N. Hayashi +5
We investigate the order parameter of noncentrosymmetric superconductors LiPdB and LiPtB via the behavior of the penetration depth . The low-temperature penet…
Relaxation properties of the quantum kinetics of carrier-LO-phonon interaction in quantum wells and quantum dots
Paul Gartner, Jan Seebeck, Frank Jahnke
The time evolution of optically excited carriers in semiconductor quantum wells and quantum dots is analyzed for their interaction with LO-phonons. Both the full two-time Green's f…
Quantum kinetic theory of phonon-assisted carrier transitions in nitride-based quantum-dot systems
J. Seebeck, T. R. Nielsen, P. Gartner +1
A microscopic theory for the interaction of carriers with LO phonons is used to study the ultrafast carrier dynamics in nitride-based semiconductor quantum dots. It is shown that t…
Influence of carrier-carrier and carrier-phonon correlations on optical absorption and gain in quantum-dot systems
M. Lorke, T. R. Nielsen, J. Seebeck +2
A microscopic theory is used to study the optical properties of semiconductor quantum dots. The dephasing of a coherent excitation and line-shifts of the interband transitions due…
Metal-Ferroelectric-Metal heterostructures with Schottky contacts I. Influence of the ferroelectric properties
L. Pintilie, M. Alexe
A model for Metal-Ferroelectric-Metal structures with Schottky contacts is proposed. The model adapts the general theories of metal-semiconductor rectifying contacts for the partic…
The role of primary point defects in the degradation of silicon detectors due to hadron and lepton irradiation
I. Lazanu, S. Lazanu
The principal obstacle to long-time operation of silicon detectors at the highest energies in the next generation of experiments arises from bulk displacement damage which causes s…
