Controllable patterning and CVD growth of isolated carbon nanotubes with direct parallel writing of catalyst using Dip Pen Nanolithography
Irma Kuljanishvili, Dmitriy A. Dikin, Sergey Rozhok +2
We report a process to fabricate carbon nanotubes (CNT) by chemical vapor deposition at predetermined location. This process was enabled by patterning catalyst nanoparticles direct…
The dynamics of magnetic vortex states in a single permalloy nanoparticle
Dmitry Ruzmetov, Venkat Chandrasekhar
We demonstrate a novel method allowing the study of the magnetic state dynamics of a single nanoparticle by means of electron transport measurements. Elliptical 550 nm x 240 nm per…
Conductance asymmetry in point-contacts on epitaxial thin films of Ba(FeCo)As
Manan Mehta, Goutam Sheet, D. A. Dikin +8
Point-contact spectroscopy is a powerful tool for probing superconductors. One of the most common observations in the point-contact spectra on the recently discovered ferropnictide…
Low frequency noise in ballistic Nb/Ag point contacts
Jian Wei, Goutam Sheet, Venkat Chandrasekhar
We report on the low frequency noise in the ballistic point-contacts between a silver tip and a niobium foil. The ballistic nature of the point-contacts is confirmed by Andreev ref…
