Contact resistivity and suppression of Fermi level pinning in side-contacted germanium nanowires
KRSTIC, VOJISLAV (2013)Electrical properties of contact-interfaces in germanium nanowire field effect transistor devices are studied. In contrast to planar bulk devices, it is shown that the active conduction channel and gate length extend between ... -
Controllable growth of metallic nano-helices at room temperature conditions
KRSTIC, VOJISLAV; DONEGAN, JOHN; MCCLOSKEY, DAVID (2014)We report on a method to produce multiple-pitch, regularly shaped, aligned, and freestanding metallic nano-helices at room temperature. This method overcomes the limitations of the standard glancing angle deposition approach ... -
Field-effect transistor made of individual V2O5 nanofibers
KRSTIC, VOJISLAV (American Institute of Physics, 2000)A field-effect transistor (FET) with a channel length of ~ 100 nm was constructed from a small number of individual V2O5 fibers of the cross section 1.5nm?10nm. At low temperature, the conductance increases as the gate ... -
Growth and electrical transport of germanium nanowires
KRSTIC, VOJISLAV (American Institute of Physics, 2001)Single crystalline germanium nanowires have been synthesized from gold nanoparticles based on a vapor-liquid-solid growth mechanism. Germanium powder was evaporated at 950?C, and deposited onto gold nanoparticles at 500?C ... -
Hot-Volumes as Uniform and Reproducible SERS-Detection Enhancers in Weakly-Coupled Metallic Nanohelices
KRSTIC, VOJISLAV; DONEGAN, JOHN; DUESBERG, GEORG; MC CLOSKEY, DAVID (2017)Reproducible and enhanced optical detection of molecules in low concentrations demands simultaneously intense and homogeneous electric fields acting as robust signal amplifiers. To generate such sophisticated optical ... -
In operandi observation of dynamic annealing: A case study of boron in germanium nanowire devices
KRSTIC, VOJISLAV; KRSTIC, VOJISLAV (2015)We report on the implantation of boron in individual, electrically contacted germanium nanowires with varying diameter and present a technique that monitors the electrical properties of a single device during implantation ... -
Magneto-chiral anisotropy in charge transport through single-walled carbon nanotubes
KRSTIC, VOJISLAV (American Institute of Physics, 2002)Carbon nanotubes are chiral molecular objects and therefore exist in two forms that are each other?s mirror image. Many aspects of these fascinating new materials have recently been explored but their chirality has hardly ... -
Momentum transfer from quantum vacuum to magnetoelectric matter
KRSTIC, VOJISLAV (2006)A recent publication [Phys. Rev. Lett. 92, 020404 (2004)PRLTAO0031-900710. 1103/PhysRevLett.92.020404] raises the possibility of momentum transfer from zero-point quantum fluctuations to matter, controlled by applied ... -
Nitrogen doping of metallic single-walled carbon nanotubes:n-type conduction and dipole scattering
KRSTIC, VOJISLAV (IOP Publishing, 2007)The charge transport properties of individual, metallic nitrogen doped, single-walled carbon nanotubes are investigated. It is demonstrated that n-type conduction can be achieved by nitrogen doping. Evidence was obtained ... -
Phase breaking in three-terminal contacted single-walled carbon nanotube bundles
KRSTIC, VOJISLAV (The American Physical Society, 2000)The three-terminal electrical transport through single-walled carbon nanotube bundles with low resistive metal contacts is investigated at room temperature. After correcting for the lead resistance, two-probe resistances close ... -
Role of disorder on transport in boron-doped multiwalled carbon nanotubes
KRSTIC, VOJISLAV (The American Physical Society, 2003)Electrical transport measurements on boron-doped multiwalled carbon nanotubes deposited on top of predefined electrode patterns have been performed. The temperature dependence of the conductance reveals through two-point ...
