    Dielectric control of electrostatic barriers for molecular electronics (2001)
    Woodbury, NY : American Institute of Physics (AIP)

    Notes: We describe an approach for controlling electrostatic barriers in molecular electronics devices which uses anisotropic dielectric material to modify the analytic form of the effective electrostatic interactions within the device. We study the one-dimensional geometry relevant to interfaces between carbon nanotubes and find that the bound charge induced in a uniaxial dielectric can replace the bare electrostatic interaction between charges with separation z by an effective −log(z) interaction or a confining |z| interaction. We use these models to study the depletion region formed at heterojunctions between segments of doped carbon nanotubes. © 2001 American Institute of Physics.
