Field Tuned Superconductor to Insulator Transitions in an Amorphous Film with an Imposed Multiply Connected Geometry
M. D. Stewart, Aijun Yin, J. M. Xu +1
We have observed multiple magnetic field driven superconductor to insulator transitions (SIT) in amorphous Bi films perforated with a nano-honeycomb (NHC) array of holes. The perio…
Hopping Conduction in Disordered Carbon Nanotubes
D. P. Wang, D. E. Feldman, B. R. Perkins +4
We report electrical transport measurements on individual disordered carbon nanotubes, grown catalytically in a nanoporous anodic aluminum oxide template. In both as-grown and anne…
Ordered Nano-Crystal Arrays Spontaneously Form in Films Evaporated onto Nanopore Array Substrates
Niravun Pavenayotin, M. D. Stewart, James M. Valles +2
We present SEM images of films thermally evaporated onto Anodic Aluminum Oxide substrates that are patterned with a hexagonal array of 34 and 80 nm diameter holes spaced by 100 nm.…
Magnetic Flux Periodic Response of Nano-perforated Ultrathin Superconducting Films
M. D. Stewart, Zhenyi Long, James M. Valles +2
We have patterned a hexagonal array of nano-scale holes into a series of ultrathin, superconducting Bi/Sb films with transition temperatures 2.65 K 5 K. These regular p…
