Mobility and Saturation Velocity in Graphene on SiO2

open access: yes, 2010
We examine mobility and saturation velocity in graphene on SiO2 above room temperature (300-500 K) and at high fields (~1 V/um). Data are analyzed with practical models including gated carriers, thermal generation, "puddle" charge, and Joule heating ...

Epitaxial aluminium-nitride tunnel barriers grown by nitridation with a plasma source

open access: yes, 2007
High critical current-density (10 to 420 kA/cm^2) superconductor-insulator-superconductor tunnel junctions with aluminium nitride barriers have been realized using a remote nitrogen plasma from an inductively coupled plasma source operated in a pressure ...
