Abstract :
A distributed contact model is presented for a 1-D quasi-ballistic conductor deriving a contact resistance versus contact length as a hyperbolic cotangent relationship in terms of the quantum of resistance, the coupling conductance gc of the contact, and the ballistic mean free path (λb). The model gave excellent fits to recent contact resistance-versus-contact length data for carbon nanotubes giving gc = 2 μS/nm and λb = 380 nm.
