Influence of Contacts and Applied Voltage on a Structure of a Single GaN Nanowire
Sergey Lazarev, Luca Gelisio, Young Yong Kim +11
Semiconductor nanowires (NWs) have a broad range of applications for nano- and optoelectronics. The strain field of gallium nitride (GaN) NWs could be significantly changed when co…
Implementing an insect brain computational circuit using III-V nanowire components in a single shared waveguide optical network
David O. Winge, Steven Limpert, Heiner Linke +4
Recent developments in photonics include efficient nanoscale optoelectronic components and novel methods for sub-wavelength light manipulation. Here, we explore the potential offer…
Charge separation in donor-C60 complexes with real-time Green's functions: The importance of nonlocal correlations
E. Viñas Boström, A. Mikkelsen, C. Verdozzi +2
We use the Nonequilibrium Green's Function (NEGF) method to perform real-time simulations of the ultrafast electron dynamics of photoexcited donor-C60 complexes modeled by a Parise…
Time-resolved spectroscopy at surfaces and adsorbate dynamics: insights from a model-system approach
Emil Boström, Anders Mikkelsen, Claudio Verdozzi
We introduce a model description of femtosecond laser induced desorption at surfaces. The substrate part of the system is taken into account as a (possibly semi-infinite) linear ch…
Photoemission electron microscopy of localized surface plasmons in silver nanostructures at telecommunication wavelengths
Erik Mårsell, Esben W. Larsen, Cord L. Arnold +3
We image the field enhancement at Ag nanostructures using femtosecond laser pulses with a center wavelength of 1.55 micrometer. Imaging is based on non-linear photoemission observe…
Local Density of States and Interface Effects in Semimetallic ErAs Nanoparticles Embedded in GaAs
Jason K. Kawasaki, Rainer Timm, Kris T. Delaney +3
The atomic and electronic structures of ErAs nanoparticles embedded within a GaAs matrix are examined via cross-sectional scanning tunneling microscopy and spectroscopy (XSTM/XSTS)…
