We present a combined scanning tunneling microscopy and ballistic electron emission microscopy study of electron transport across an epitaxial Pb/Si(111) interface. Experiments with a self-assembled Pb nanoscale wedge reveal the phenomenon of confinement-enhanced interfacial transport: a proportional increase of the electron injection rate into the semiconductor with the frequency of electron o...

Gold nanowires a few atomic diameters wide are observed by ultra-high vacuum transmission electron microscopy, and their conductance measured simultaneously using a scanning tunneling microscope built into the electron microscope. A strand of gold atoms suspended between electrodes is directly observed to have a conductance of 2e2/h (=(12.9 kΩ)-1), where e is the electron charge and h is Planck...

We have experimentally investigated the impact of dimensions and temperature on the thermal conductivity of silicon nanowires fabricated using a top-down approach. Both the width and temperature dependences of thermal conductivity agree with those in the existing literature. The length dependence of thermal conductivity exhibits a transition from semi-ballistic thermal phonon transport at 4 K t...

We present a simple description of ballistic transport in systems with random rough walls. All characteristic parameters, including the mean free path and localization length, are expressed explicitly via the correlation function (correlation length R and amplitude g) of surface inhomogeneities. Scattering by surfaces inhomogeneities in channels with width L creates a new mesoscopic transport l...

Single-walled carbon nanotube (SWCNTs) can be thought of as graphene a single graphene sheet wrapped up to form a one-atom-thick cylinders. CNTs were discovered by Iijima [1] in 1991, since then the excellent charge transport properties of CNTs have been of great inter‐ est, for its great potential applications in nanoelectronics, such as high-speed field-effect transistors (FETs) [2, 3], singl...

in this paper, the range doppler algorithm (rda) for synthetic aperture radar moving on a ballistic trajectory is presented. the 3-dimension acceleration and non-uniform trajectory cause decreases in efficiency of conventional imaging algorithms. in this paper, the analytical expression for the 2-d signal spectrum for ballistic trajectory using taylor series expansion and series reversion is de...

The question whether dissipative bio-molecular systems can support efficient coherent (phase-conserving) charge transport is raised again following recent experiments on electron-energy transfer in bio-molecules. In this work we formulate conditions under which the current due to coherent ballistic resonant charge transport through DNA molecular junctions can be measured in spite of coupling to...
