The Role of Quantum Effects on Structural and Electronic Fluctuations in Neat and Charged Water

Michele Ceriotti, Federico Giberti, Michele Parrinello

In this work, we revisit the role of nuclear quantum effects on the structural and electronic properties of the excess proton in bulk liquid water using advanced molecular dynamics techniques. The hydronium ion is known to be a weak acceptor of a hydrogen ...

Bandgap engineering in a nanowire: self-assembled 0, 1 and 2D quantum structures

Inherent to the nanowire morphology is the exciting possibility of fabricating materials organized at the nanoscale in three dimensions. Composition and structure can be varied along and across the nanowire, as well as within coaxial shells. This opens up ...

Quantum transport through single atoms and molecules

Yi Zhang, Klaus Kern, Peter Wahl

Experiments on quantum transport in a low temperature scanning tunneling microscope provide the possibility to study atomic and molecular contacts with well-defined electrode-geometry at least for one of the contacts, the surface. Here, we show for a numbe ...

Quantum Wire - Quantum Dot Systems Grown in Inverted Pyramids

Justyna Szeszko

Semiconductor quantum wires (QWRs) and quantum dots (QDs) are nanoscale heterostructures, which form fascinating low-dimensional systems for fundamental studies of quantum-mechanical effects and are attractive candidates for integration into optoelectronic ...

Formation of Fe Cluster Superlattice in a Metal-Organic Quantum-Box Network

Harald Brune, Marina Pivetta, Uta Schlickum, Giulia Elisabetta Pacchioni

We report on the self-assembly of Fe adatoms on a Cu(111) surface that is patterned by a metal-organic honeycomb network, formed by coordination of dicarbonitrile pentaphenyl molecules with Cu adatoms. Fe atoms landing on the metal surface are mobile and s ...

Quantum Mechanical Study of the Germanium Electron-Hole Bilayer Tunnel FET

Mihai Adrian Ionescu, Luca De Michielis, Cem Alper, Livio Lattanzio, Pierpaolo Palestri, Luca Selmi

The electron-hole bilayer tunnel field-effect transistor (EHBTFET) is an electronic switch that uses 2-D-2-D sub-band-to-sub-band tunneling (BTBT) between electron and hole inversion layers and shows significant subthermal swing over several decades of cur ...

Dilute-Nitride Low-Dimensional Nanostructures Formed on Non-Planar Substrates

Romain Carron

The properties of semiconductors heterostructures of nanoscopic dimensions change from that of bulk material according to the rules of quantum mechanics. The planar quantum wells (QWs) are widely used in various diode and laser devices thanks to the relati ...

Enhanced superradiance in epsilon-near-zero plasmonic channels

Romain Christophe Rémy Fleury

We describe the possibility of drastically boosting the spontaneous emission of a collection of two-level quantum emitters by embedding them in an epsilon-near-zero (ENZ) environment, consisting of a plasmonic waveguide operated at cutoff. This phenomenon ...

Exciton Dynamics in Suspended Monolayer and Few-Layer MoS2

Andras Kis, Simone Bertolazzi, Jacopo Brivio

Femtosecond transient absorption spectroscopy and microscopy were employed to study exciton dynamics in suspended and Si3N4 substrate-supported monolayer and few-layer MoS2 2D crystals. Exciton dynamics for the monolayer and few-layer structures were found ...

Critical Resistance at the Superconductor-Insulator Transition in Hole-Doped Cuprates

Davor Pavuna, Guy Joseph Günter Dubuis, Ivan Bozovic

Here, we show that in several p-type cuprates, the superconductor-to-insulator transition (SIT) occurs at the critical sheet resistance approximately equal to the quantum resistance of pairs, RQ=h/4

e^{2}

=6.5 kΩ. In a relatively broad range of temperature ...
