Moving beyond the limits of silicon transistors requires both a high-performance channel and high-quality electrical contacts. Carbon nanotubes provide high-performance channels below 10 nanometers, but as with silicon, the increase in contact resistance with decreasing size becomes a major performance roadblock. We report a single-walled carbon nanotube (SWNT) transistor technology with an end...

The impact of the intrinsic time-dependent fluctuations in the electrical resistance at the graphene-metal interface or the contact noise, on the performance of graphene field-effect transistors, can be as adverse as the contact resistance itself, but remains largely unexplored. Here we have investigated the contact noise in graphene field-effect transistors of varying device geometry and conta...

The effective conductivity of material systems consisting of contacting particles is studied computationally using a model of monodisperse circular disks. The electrical or thermal conductivity is computed by modeling the relevant mechanical contact problem followed by a steady-state conduction analysis. The interparticle contact resistance is incorporated via the introduction of gap conductanc...

In a flip-chip-on-glass (FCOG) assembly, anisotropic conductive film (ACF) is used as the adhesive to bind the desired interconnection between the flip chip and glass substrate. However, it remains a challenge to develop the ACF bonded flip chip packages with low contact resistance. Considerable research has been conducted recently to investigate the effect of different parameters on the contac...

To use e-textiles as a strain-resistance sensor they need to be both elastic and conductive. Three kinds of elastic-conductive webbings, including flat, tubular, and belt webbings, made of Lycra fiber and carbon coated polyamide fiber, were used in this study. The strain-resistance properties of the webbings were evaluated in stretch-recovery tests and measured within 30% strain. It was found t...
