Lingering Times at Resonance: The Case of Sb-based Tunneling Devices
Edgar David Guarin Castro, Andreas Pfenning, Fabian Hartmann +7
Concurrent natural time scales related to relaxation, recombination, trapping, and drifting processes rule the semiconductor heterostructures' response to external drives when char…
Optical mapping of non-equilibrium charge carriers
E. David Guarin Castro, A. Pfenning, F. Hartmann +6
We investigate the energy relaxation segmentation in a resonant tunneling heterostructures by assessing the optical and transport dynamics of non-equilibrium charge carriers. The e…
Phonon-assisted exciton and trion conversion efficiency in transition metal Dichalcogenides
Sabrine Ayari, Sihem Jaziri, Robson Ferreira +1
Photoluminescence spectra, shows that monolayer Transition-metal dichalcogenides (MLTMDCs), possess charged exciton binding energies, conspicuously similar to the energy of optical…
Avoided level crossing at the magnetic field induced topological phase transition due to spin-orbital mixing
G. Krizman, B. A. Assaf, M. Orlita +7
In 3D topological insulators, an effective closure of the bulk energy gap with increasing magnetic field expected at a critical point can yield a band crossing at a gapless Dirac n…
Tunable Dirac interface states in topological superlattices
G. Krizman, B. A. Assaf, T. Phuphachong +6
Relativistic Dirac fermions are ubiquitous in condensed matter physics. Their mass is proportional to the material energy gap and the ability to control and tune the mass has becom…
Free carrier absorption in cascade structures due to static scatterers in the in-plane polarization
Camille Ndebeka-Bandou, Francesca Carosella, Robson Ferreira +1
We report on the computation of the free carrier absorption induced by static scatterers in cascade structures when the electromagnetic wave propagates along the growth axis. We fi…
