The relationship between contact resistance and contact force on Au coated carbon nanotube surfaces under low force conditions
The relationship between contact resistance and contact force on Au coated carbon nanotube surfaces under low force conditions
Carbon-Nanotube (CNT) coated surfaces are investigated to determine the
electrical contact performance under low force conditions. The surfaces under investigation
are vertically aligned multi-walled CNTs formed on a Silicon substrate and coated with an
Au film. These planar surfaces are mated with a hemispherical Au plated probe mounted in
a nano-indentation apparatus. The maximum contact force used is 1mN. The contact
resistance of these surfaces is investigated as a function of the applied force and is also
studied under repeated loading cycles. The surfaces are compared with a reference Au-Au
contact under the same experimental conditions and the results compared to established
contact theory. The results show that the vertically aligned multi-walled CNT surface
provides a stable contact resistance. This study shows the potential for the application of
CNT surfaces as an interface in low force electrical contact applications.

Abstract
Carbon-Nanotube (CNT) coated surfaces are investigated to determine the
electrical contact performance under low force conditions. The surfaces under investigation
are vertically aligned multi-walled CNTs formed on a Silicon substrate and coated with an
Au film. These planar surfaces are mated with a hemispherical Au plated probe mounted in
a nano-indentation apparatus. The maximum contact force used is 1mN. The contact
resistance of these surfaces is investigated as a function of the applied force and is also
studied under repeated loading cycles. The surfaces are compared with a reference Au-Au
contact under the same experimental conditions and the results compared to established
contact theory. The results show that the vertically aligned multi-walled CNT surface
provides a stable contact resistance. This study shows the potential for the application of
CNT surfaces as an interface in low force electrical contact applications.
