Lateral Mn5Ge3 spin-valve in contact with a high-mobility Ge two-dimensional hole gas
David Weißhaupt, Christoph Sürgers, Dominik Bloos +8
Ge two-dimensional hole gases in strained modulation-doped quantum-wells represent a promising material platform for future spintronic applications due to their excellent spin tran…
Theory of charge-spin conversion at oxide interfaces: The inverse spin-galvanic effect
Goetz Seibold, Sergio Caprara, Roberto Raimondi
We evaluate the non-equilibrium spin polarization induced by an applied electric field for a tight-binding model of electron states at oxides interfaces in LAO/STO heterostructures…
Graphene enhanced field emission from InP nanocrystals
L. Iemmo, A. Di Bartolomeo, F. Giubileo +6
We report the observation of field emission from InP nanocrystals epitaxially grown on an array of p-Si nanotips. We prove that field emission can be enhanced by covering the InP n…
Theory of the spin galvanic effect at oxide interfaces
G. Seibold, S. Caprara, M. Grilli +1
The spin galvanic effect (SGE) describes the conversion of a non-equilibrium spin polarization into a transverse charge current. Recent experiments have demonstrated a large conver…
Density inhomogeneities and Rashba spin-orbit coupling interplay in oxide interfaces
N. Bovenzi, S. Caprara, M. Grilli +3
There is steadily increasing evidence that the two-dimensional electron gas (2DEG) formed at the interface of some insulating oxides like LaAlO3/SrTiO3 and LaTiO3/SrTiO3 is strongl…
Hybrid Graphene/Silicon Schottky photodiode with intrinsic gating effect
Antonio Di Bartolomeo, Giuseppe Luongo, Filippo Giubileo +5
We propose a hybrid device consisting of a graphene/silicon (Gr/Si) Schottky diode in parallel with a Gr/SiO2/Si capacitor for high-performance photodetection. The device, fabricat…
Observation of field emission from GeSn nanoparticles epitaxially grown on silicon nanopillar arrays
Antonio Di Bartolomeo, Maurizio Passacantando, Gang Niu +4
We apply molecular beam epitaxy to grow GeSn-nanoparticles on top of Si-nanopillars patterned onto p-type Si wafers. We use X-ray photoelectron spectroscopy to confirm a metallic b…
Tunable Schottky barrier and high responsivity in graphene/Si-nanotip optoelectronic device
Antonio Di Bartolomeo, Filippo Giubileo, Giuseppe Luongo +7
We demonstrate tunable Schottky barrier height and record photo-responsivity in a new-concept device made of a single-layer CVD graphene transferred onto a matrix of nanotips patte…
Graphene field effect transistors with Niobium contacts and asymmetric transfer characteristics
Antonio Di Bartolomeo, Filippo Giubileo, Francesco Romeo +5
We fabricate back-gated field effect transistors using Niobium electrodes on mechanically exfoliated monolayer graphene and perform electrical characterization in the pressure rang…
Intrinsic spin Hall effect in systems with striped spin-orbit coupling
Goetz Seibold, Sergio Caprara, Marco Grilli +1
The Rashba spin-orbit coupling arising from structure inversion asymmetry couples spin and momentum degrees of freedom providing a suitable (and very intensively investigated) envi…
Possible mechanisms of electronic phase separation in oxide interfaces
N. Bovenzi, F. Finocchiaro, N. Scopigno +4
LaAlO3/SrTiO3 ad LaTiO3/SrTiO3 interfaces are known to host a strongly inhomogeneous (nearly) two-dimensional electron gas (2DEG). In this work we present three unconventional elec…
Phase separation and long wave-length charge instabilities in spin-orbit coupled systems
G. Seibold, D. Bucheli, S. Caprara +1
We investigate a two-dimensional electron model with Rashba spin-orbit interaction where the coupling constant depends on the electronic density. It is shown that this dep…
Phase diagrams of voltage-gated oxide interfaces with strong Rashba coupling
D. Bucheli, M. Grilli, F. Peronaci +2
We propose a model for the two-dimensional electron gas formed at the interface of oxide heterostructures that includes a Rashba spin-orbit coupling proportional to an electric fie…
Fano Regime of Transport through Open Quantum Dots
E. R. Racec, U. Wulf, P. N. Racec
We analyze a quantum dot strongly coupled to the conducting leads via quantum point contacts - Fano regime of transport - and report a variety of resonant states which demonstrate…
R-matrix formalism for electron scattering in two dimensions
P. N. Racec, E. R. Racec, H. Neidhardt
We investigate the scattering phenomena in two dimensions produced by a general finite-range nonseparable potential. This situation can appear either in a Cartesian geometry or in…
Admittance of planar two-terminal quantum systems
U. Wulf, P. N. Racec, E. R. Racec
We develop an approach to calculate the admittance of effectively one-dimensional open quantum systems in random phase approximation. The stationary, unperturbed system is describe…
Pulse Propagation in Resonant Tunneling
Ulrich Wulf, V. V. Skalozub
We consider the analytically solvable model of a Gaussian pulse tunneling through a transmission resonance with a Breit-Wigner characteristic. The solution allows for the identific…
Resonant transport throught semiconductor nanostructures
E. R. Racec, P. N. Racec, U. Wulf
Transport through semiconductor nanostructures is a quantum-coherent process. This paper focuses on systems in which the electron's dynamics is ballistic and the transport is domin…
