Magnetic field tuned superconductor-to-insulator transition at the LaAlO /SrTiO interface
M. M. Mehta, D. A. Dikin, C. W. Bark +4
We present a study of the magnetic field tuned superconductor-to-insulator transition (SIT) in the electron gas that forms at the LaAlO/SrTiO interface. We find that the ma…
Coexistence of superconductivity and ferromagnetism in two dimensions
D. A. Dikin, M. Mehta, C. W. Bark +3
Ferromagnetism is usually considered to be incompatible with conventional superconductivity, as it destroys the singlet correlations responsible for the pairing interaction. Superc…
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…
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…
Phase-incoherent superconducting pairs in the normal state of Ba(FeCo)As
Goutam Sheet, Manan Mehta, D. A. Dikin +8
The normal state properties of the recently discovered ferropnictide superconductors might hold the key to understanding their exotic superconductivity. Using point-contact spectro…
Simple approach for high-contrast optical imaging and characterization of graphene-based sheets
Inhwa Jung, Matthew Pelton, Richard Piner +5
A simple optical method is presented for identifying and measuring the effective optical properties of nanometer-thick, graphene-based materials, based on the use of substrates con…
