Fundamental limits in heat assisted magnetic recording and methods to overcome it with exchange spring structures
Dieter Suess, Christoph Vogler, Claas Abert +3
The switching probability of magnetic elements for heat assisted recording is investigated. It is found that FePt elements with a diameter of 5 nm and a height of 10nm show, at a f…
Graphene quantum dot on boron nitride: Dirac cone replica and Hofstadter butterfly
L. A. Chizhova, F. Libisch, J. Burgdörfer
Graphene flakes placed on hexagonal boron nitride feature in the presence of a magnetic field a complex electronic structure due to a hexagonal moiré potential resulting from the v…
NBTI in Nanoscale MOSFETs - The Ultimate Modeling Benchmark
Tibor Grasser, Karina Rott, Hans Reisinger +3
After nearly half a century of research into the bias temperature instability (BTI), two classes of models have emerged as the strongest contenders: one class of models, the reacti…
A density functional theory based direct comparison of coherent tunnelling and electron hopping in redox-active single molecule junctions
Georg Kastlunger, Robert Stadler
For defining the conductance of single molecule junctions with a redox functionality in an electrochemical cell, two conceptually different electron transport mechanisms, namely co…
Ab-initio friction forces on the nanoscale: A DFT study of fcc Cu(111)
Michael Wolloch, Gregor Feldbauer, Peter Mohn +2
While there are a number of models that tackle the problem of calculating friction forces on the atomic level, providing a completely parameter-free approach remains a challenge. H…
Imaging the dynamics of free-electron Landau states
P. Schattschneider, Th. Schachinger, M. Stöger-Pollach +4
Landau levels and states of electrons in a magnetic field are fundamental quantum entities underlying the quantum-Hall and related effects in condensed matter physics. However, the…
Diffractive wave guiding of hot electrons by the Au (111) herringbone reconstruction
F. Libisch, V. Geringer, D. Subramaniam +2
The surface potential of the herringbone reconstruction on Au(111) is known to guide surface-state electrons along the potential channels. Surprisingly, we find by scanning tunneli…
Modulation of electronic and mechanical properties of phosphorene through strain
Mohammad Elahi, Kaveh Khaliji, Seyed Mohammad Tabatabaei +2
We report a first-principles study on the elastic, vibrational, and electronic properties of recently synthesized phosphorene. By calculating Grüneisen parameters, we evaluate the…
Characterizing wave functions in graphene nanodevices: electronic transport through ultrashort graphene constrictions on a boron nitride substrate
Dominik Bischoff, Florian Libisch, Joachim Burgdörfer +2
We present electronic transport measurements through short and narrow (30x30 nm) single layer graphene constrictions on a hexagonal boron nitride substrate. While the general obser…
Mechanisms of photoconductivity in atomically thin MoS2
Marco M. Furchi, Dmitry K. Polyushkin, Andreas Pospischil +1
Atomically thin transition metal dichalcogenides have emerged as promising candidates for sensitive photodetection. Here, we report a photoconductivity study of biased mono- and bi…
Photovoltaic effect in an electrically tunable van der Waals heterojunction
Marco M. Furchi, Andreas Pospischil, Florian Libisch +2
Semiconductor heterostructures form the cornerstone of many electronic and optoelectronic devices and are traditionally fabricated using epitaxial growth techniques. More recently,…
Negative quantum capacitance in graphene nanoribbons with lateral gates
R. Reiter, U. Derra, S. Birner +4
We present numerical simulations of the capacitive coupling between graphene nanoribbons of various widths and gate electrodes in different configurations. We compare the influence…
Anomalous diameter dependence of thermal transport in ultra-narrow Si nanowires
Hossein Karamitaheri, Neophytos Neophytou, Hans Kosina
We present atomistic valence force field calculations of thermal transport in Si nanowires of diameters from 12nm down to 1nm. We show that as the diameter is reduced, the phonon d…
