摘要

RF MEMS capacitive switches using leaky nanodiamond as a dielectric film are studied and compared with those using Si3N4. Characteristics of dielectric charging and discharging are analyzed at temperature ranging from - 196 °C to 150 °C. Electrical resistivity of leaky nanodiamond is measured to be lower than that of Si3N 4 by 3 to 6 orders of magnitude at room temperature. Trapped charges in leaky nanodiamond dielectric discharge much more quickly than those in Si3N4 while the power dissipation of nanodiamond based switches remains low. As a result, charge trapping induced shift in electrostatic actuation voltage is greatly reduced compared to that with Si 3N4 and becomes non-detectable under the reported conditions. RF MEMS capacitive switches based on leaky nanodiamond dielectric are, therefore, more reliable than those with Si3N4.
