Direct chemical and structural characterization of transient iron-nickel alloy nanowires with diameter < 2 nm was performed at sub-nanometer spatial resolution using probe spherical aberration-corrected Scanning Transmission Electron Microscopy and…

Single-atom-width gold wires were produced by stretching gold nanocontacts using piezomanipulation inside a high-resolution transmission electron microscope. The structure of the wires was observed in situ with simultaneous conductance measurements.…

The deformation behavior of nanoparticles continues to be an exciting area for materials research. Typically, nanoparticles show a conspicuous lack of dislocations, even after significant deformation. Therefore, it has been suggested that…

Under GGA, the structural, electronic and magnetic properties of single-wall (8,8) GeC nanotubes filled with iron Fen nanowires (n=5, 9, 13 and 21) have been investigated systematically using the first-principles PAW potential within DFT. We find…

Metal contacts are regarded as key elements of nanometer-scale electronics. Since gold contacts show quantized conductance even at room temperature, much effort has been devoted to understand their conductance behavior on the nanoscale. However,…

Electrically driven gallium movement in carbon nanotubes is discussed. A higher current (∼15 mA) makes the gallium migrate sharply toward the anode, which increases its mass transport speed with time in the range of 0 to more than 10.345 fg s(-1).…

Electron emission from individual graphene nanoribbons (GNRs) driven by internal electric field was studied for the first time inside a high resolution transmission electron microscope (TEM) equipped with a state-of-art scanning tunneling microscope…

A nanoscale thermocouple consisting of merged Cu and Cu-Ni tips is developed for local temperature measurements on advanced nanomaterials by using a probing technique in a high-resolution transmission electron microscope (TEM) equipped with a double…

In this work, reversible synthetic nano rocket-like behavior of indium-filled indium oxide nanotubes is reported once irradiated with high energy electron beam during transmission electron microscopy study. These rocket-like nanostructures were…

Piezoelectric nanoactuators, which can provide extremely stable and reproducible positioning, are rapidly becoming the dominant means for position control in transmission electron microscopy. Here we present a second-generation miniature goniometric…
