Electroluminescence in Single Layer MoS2
R. S. Sundaram, M. Engel, A. Lombardo +4
We detect electroluminescence in single layer molybdenum disulphide (MoS2) field-effect transistors built on transparent glass substrates. By comparing absorption, photoluminescenc…
Massively parallel Monte Carlo for many-particle simulations on GPUs
Joshua A. Anderson, Eric Jankowski, Thomas L. Grubb +2
Current trends in parallel processors call for the design of efficient massively parallel algorithms for scientific computing. Parallel algorithms for Monte Carlo simulations of th…
Hard-disk equation of state: First-order liquid-hexatic transition in two dimensions with three simulation methods
Michael Engel, Joshua A. Anderson, Sharon C. Glotzer +3
We report large-scale computer simulations of the hard-disk system at high densities in the region of the melting transition. Our simulations reproduce the equation of state, previ…
Confirmation of the random tiling hypothesis for a decagonal quasicrystal
Alexander Kiselev, Michael Engel, Hans-Rainer Trebin
Mechanisms that stabilize quasicrystals are much discussed but not finally resolved. We confirm the random tiling hypothesis and its predictions in a fully atomistic decagonal quas…
High-frequency performance of scaled carbon nanotube array field-effect transistors
Mathias Steiner, Michael Engel, Yu-Ming Lin +10
We report the radio-frequency performance of carbon nanotube array transistors that have been realized through the aligned assembly of highly separated, semiconducting carbon nanot…
