Gate Coupling to Nanoscale Electronics
Sujit S. Datta, Douglas R. Strachan, A. T. Charlie Johnson
The realization of single-molecule electronic devices, in which a nanometer-scale molecule is connected to macroscopic leads, requires the reproducible production of highly ordered…
Surface Potentials and Layer Charge Distributions in Few-Layer Graphene Films
Sujit S. Datta, Douglas R. Strachan, E. J. Mele +1
Graphene-derived nanomaterials are emerging as ideal candidates for postsilicon electronics. Elucidating the electronic interaction between an insulating substrate and few-layer gr…
Crystallographic Etching of Few-Layer Graphene
Sujit S. Datta, Douglas R. Strachan, Samuel M. Khamis +1
We demonstrate a method by which few-layer graphene samples can be etched along crystallographic axes by thermally activated metallic nanoparticles. The technique results in long (…
Two Distinct Time-Scale Regimes of the Effective Temperature for an Aging Colloidal Glass
D. R. Strachan, G. C. Kalur, S. R. Raghavan
Colloidal dispersions of Laponite platelets are known to age slowly from viscous sols to colloidal glasses. We follow this aging process by monitoring the diffusion of probe partic…
Effects of Self-field and Low Magnetic Fields on the Normal-Superconducting Phase Transition
M. C. Sullivan, D. R. Strachan, T. Frederiksen +2
Researchers have studied the normal-superconducting phase transition in the high- cuprates in a magnetic field (the vortex-glass or Bose-glass transition) and in zero field. O…
Controlled Fabrication of Nanogaps in Ambient Environment for Molecular Electronics
D. R. Strachan, D. E. Smith, D. E. Johnston +4
We have developed a controlled and highly reproducible method of making nanometer-spaced electrodes using electromigration in ambient lab conditions. This advance will make feasibl…
