Contact resistivity and suppression of Fermi level pinning in side-contacted germanium nanowires
(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 ... -
Electron and spin transport studies of gated lateral organic devices
(2012)In view of the many, often contradictory, reports of magneto-resistance (M R) in spin valve stacks containing a layer of organic semiconductor, mostly of the small molecule variety, we have investigated interdigitated ... -
Microscopic mechanism of electron transfer through the hydrogen bonds between carboxylated alkanethiol molecules connected to gold electrodes
(2014)The atomic structure and the electron transfer properties of hydrogen bonds formed between two carboxylated alkanethiol molecules connected to gold electrodes are investigated by employing the non-equilibrium Green's ... -
Microscopic origin of the 1.3 G0 conductance observed in oxygen-doped silver quantum point contacts
(2014)Besides the peak at one conductance quantum, G0, two additional features at ∼0.4 G0 and ∼1.3 G0 have been observed in the conductance histograms of silver quantum point contacts at room temperature in ambient conditions. ... -
Quantitative interpretation of the transition voltages in gold-poly(phenylene) thiol-gold molecular junctions
(2013)The transition voltage of three different asymmetric Au/poly(phenylene) thiol/Au molecular junctions in which the central molecule is either benzene thiol, biphenyl thiol, or terphenyl thiol is investigated by first-principles ... -
Transition voltages of vacuum-spaced and molecular junctions with Ag and Pt electrodes
(2014)The transition voltage of vacuum-spaced and molecular junctions constructed with Ag and Pt electrodes is investigated by non-equilibrium Green's function formalism combined with density functional theory. Our calculations ...
