The optical absorption in indirect semiconductor to semimetal PtSe2 arises from direct transitions
Marin Tharrault, Sabrine Ayari, Mehdi Arfaoui +12
is a van der Waals material transitioning from an indirect bandgap semiconductor to a semimetal with increasing thickness. Its absorption threshold has been conjectur…
Electroluminescence and Energy Transfer Mediated by Hyperbolic Polaritons
L. Abou-Hamdan, A. Schmitt, R. Bretel +26
Under high electrical current, some materials can emit electromagnetic radiation beyond incandescence. This phenomenon, referred to as electroluminescence, leads to the efficient e…
High-sensitivity AC-charge detection with a MHz-frequency fluxonium qubit
B. -L. Najera-Santos, R. Rousseau, K. Gerashchenko +15
Owing to their strong dipole moment and long coherence times, superconducting qubits have demonstrated remarkable success in hybrid quantum circuits. However, most qubit architectu…
Electroluminescence of the graphene 2D semi-metal
A. Schmitt, L. Abou-Hamdan, M. Tharrault +18
Electroluminescence, a non-thermal radiative process, is ubiquitous in semi-conductors and insulators but fundamentally precluded in metals. We show here that this restriction can…
Top-down integration of a hBN quantum emitter in a monolithic photonic waveguide
Domitille Gérard, Michael Rosticher, Kenji Watanabe +5
Integrated quantum photonics, with potential applications in quantum information processing, relies on the integration of quantum emitters into on-chip photonic circuits. Hexagonal…
Magneto-exciton limit of quantum Hall breakdown in graphene
A. Schmitt, M. Rosticher, T. Taniguchi +8
One of the intrinsic drift velocity limit of the quantum Hall effect is the collective magneto-exciton (ME) instability. It has been demonstrated in bilayer graphene (BLG) using no…
Velocity and confinement of edge plasmons in HgTe-based 2D topological insulators
Alexandre Gourmelon, Elric Frigerio, Hiroshi Kamata +10
High-frequency transport in the edge states of the quantum spin Hall (QSH) effect has to date rarely been explored, though it could cast light on the scattering mechanisms taking p…
High-field 1/f noise in hBN-encapsulated graphene transistors
A. Schmitt, D. Mele, M. Rosticher +11
Low-frequency 1/f noise in electronics is a conductance fluctuation, that has been expressed in terms of a mobility "-noise" by Hooge and Kleinpenning. Understanding this noise…
