Preparation of atomically-flat SrTiO3 surfaces using a deionized-water etching and thermal annealing procedure
J. G. Connell, B. J. Isaac, D. R. Strachan +1
We report that a deionized water etching and thermal annealing technique can be effective for preparing atomically-flat and singly-terminated surfaces of single crystalline SrTiO3…
High On/Off Ratio Graphene Nanoconstriction Field Effect Transistor
Ye Lu†, Brett Goldsmith†, Douglas R. Strachan†‡ +3
We report a method to pattern monolayer graphene nanoconstriction field effect transistors (NCFETs) with critical dimensions below 10 nm. NCFET fabrication is enabled by the use of…
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…
