Scanning gate experiments: from strongly to weakly invasive probes
R. Steinacher, C. Pöltl, T. Krähenmann +8
An open resonator fabricated in a two-dimensional electron gas is used to explore the transition from strongly invasive scanning gate microscopy to the perturbative regime of weak…
Correlation between peak-height modulation and phase-lapses in transport through quantum dots
Rodolfo A. Jalabert, Rafael A. Molina, Guillaume Weick +1
We show that two intriguing features of mesoscopic transport, namely the modulation of Coulomb blockade peak-heights and the transmission phase-lapses occurring between subsequent…
Retardation effects on the dispersion and propagation of plasmons in metallic nanoparticle chains
Charles A. Downing, Eros Mariani, Guillaume Weick
We consider a chain of regularly-spaced spherical metallic nanoparticles, where each particle supports three degenerate localized surface plasmons. Due to the dipolar interaction b…
Localization of massless Dirac particles via spatial modulations of the Fermi velocity
C. A. Downing, M. E. Portnoi
The electrons found in Dirac materials are notorious for being difficult to manipulate due to the Klein phenomenon and absence of backscattering. Here we investigate how spatial mo…
Spin-relaxation time in the impurity band of wurtzite semiconductors
Pablo I. Tamborenea, Thomas Wellens, Dietmar Weinmann +1
The spin-relaxation time for electrons in the impurity band of semiconductors with wurtzite crystal structure is determined. The effective Dresselhaus spin-orbit interaction Hamilt…
Partial local density of states from scanning gate microscopy
Ousmane Ly, Rodolfo A. Jalabert, Steven Tomsovic +1
Scanning gate microscopy images from measurements made in the vicinity of quantum point contacts were originally interpreted in terms of current flow. Some recent work has analytic…
Electrical single spin read-out using an exchange-coupled quantum dot
Clément Godfrin, Stefan Thiele, Karim Ferhat +4
We present a new way of continuously reading-out the state of a single electronic spin. Our detection scheme is based on an exchange interaction between the electronic spin and a n…
Radiative frequency shifts in nanoplasmonic dimers
Charles A. Downing, Eros Mariani, Guillaume Weick
We study the effect of the electromagnetic environment on the resonance frequency of plasmonic excitations in dimers of interacting metallic nanoparticles. The coupling between pla…
Exploring coherence of individual excitons in InAs quantum dots embedded in natural photonic defects: influence of the excitation intensity
Daniel Wigger, Valentin Delmonte, Quentin Mermillod +10
The exact optical response of quantum few-level systems depends crucially on the exact choice of the incoming pulse areas. We use four-wave mixing (FWM) spectroscopy to infer the c…
Imaging isodensity contours of molecular states with STM
Gaël Reecht, Benjamin Heinrich, Hervé Bulou +3
We present an improved way for imaging the local density of states with a scanning tunneling microscope, which consists in mapping the surface topography while keeping the differen…
Charge versus energy transfer in atomically-thin graphene-transition metal dichalcogenide van der Waals heterostructures
Guillaume Froehlicher, Etienne Lorchat, Stéphane Berciaud
Van der Waals heterostuctures, made from stacks of two-dimensional materials, exhibit unique light-matter interactions and are promising for novel optoelectronic devices. The perfo…
Conductance oscillations in graphene/nanoclusters hybrid material: towards large area single electron devices
Florian Godel, Louis Donald Notemgnou Mouafo, Guillaume Froehlicher +5
Large assemblies of self-organized aluminum nanoclusters embedded in an oxide layer are formed on graphene templates and used to build tunnel-junction devices. Unexpectedly, single…
Domain wall architecture in tetragonal ferroelectric thin films
Gabriele De Luca, Marta D. Rossell, Jakob Schaab +3
Domain walls in ferroelectrics exhibit a plethora of phases and functionalities not found in the bulk. The interplay of electrostatic, chemical, topological, and distortive inhomog…
Quantum interference effects in resonant Raman spectroscopy of single- and triple-layer MoTe from first principles
Henrique P. C. Miranda, Sven Reichardt, Guillaume Froehlicher +3
We present a combined experimental and theoretical study of resonant Raman spectroscopy in single- and triple-layer MoTe. Raman intensities are computed entirely from first pri…
