Interaction between interface and massive states in multivalley topological heterostructures
Gauthier Krizman, Badih A. Assaf, Milan Orlita +5
Topological interface states in multivalley systems are studied to unravel their valley sensitivity. For this purpose, multivalley IV-VI topological crystalline insulator (TCI) het…
Ultrasensitive Photoresponse of Graphene Quantum Dot in the Coulomb Blockade Regime to THz Radiation
E. Riccardi, S. Massabeau, F. Valmorra +11
Graphene quantum dots (GQDs) have recently attracted considerable attention, with appealing properties for terahertz (THz) technology. This includes the demonstration of large ther…
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…
Giant optical nonlinearity cancellation in quantum wells
S. Houver, A. Lebreton, T. A. S. Pereira +10
Second-order optical nonlinearities can be greatly enhanced by orders of magnitude in resonantly excited nanostructures, theoretically predicted and experimentally investigated in…
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…
