AuxAg1-x alloy seeds: A way to control growth, morphology and defect formation in Ge nanowiress

Biswas S., Holmes J.D., University College Cork, IE

Ge nanowires are of current interest for high speed nanoelectronic devices due to the lower band gap and high carrier mobility and larger excitonic Bohr radius of Ge yields a more pronounced quantum confinement effect.Most [...]

Deposition and Characterization of Platinum Nanoparticles on Highly Orientated Pyrolytic Graphite

Elizondo-Villarreal N., Novar C., Zhou J.P., Alvarez Contreras L., Tel Vered R., Universidad Autonoma de Nuevo Leon, MX

Platinum is considered one of the best electrocatalyst for low temperature reactions in a H2/O2 fuel cell. Metallic nanoparticles are of great interest because of the modification of properties observed due to size effects, modifying [...]

Tracking the Formation of a Break Junction Formed by Electromigration using Transmission Electron Microscopy

Dong J., Parviz B.A., University of Washington, US

Break junctions formed by electromigration have been extensively used in the molecular electronics and electrical characterization of atomic or molecular clusters and biological molecules such as deoxyribonucleic acid (DNA)1. However, to obtain a controllable gap [...]

Lattice Fringe Fingerprinting in Two Dimensions with Database Support

Moeck P., Seipel B., Bjorge R., Fraundorf P., Portland State University, US

Direct space high-resolution phase-contrast transmission electron microscopy (HRTEM) and atomic resolution Z-contrast scanning TEM (Z-STEM), when combined with tools for image-based nanocrystallography possess the capacity to derive the crystallographic phase and shape of nanocrystals. This [...]
