| Research Abstract |
Radio-frequency microelectromechanical systems (RF MEMS) switches have potentially superior electrical properties. There are problems with the electrical contacts: The mechanical relay switches in RF MEMS switches are microsized, and so the contact electrodes must be considerably smaller (less than 100 μm2) . In order to solve the problem, we used carbon nanotube (CNT) films as contact materials under micro loads. Although CNT films have high contact resistances, Au film depositions on CNT films and horizontal alignment of CNTs decrease contact resistances.
