Carbon nanotube forests as top electrode in electroacoustic resonators

Abstract
We grow carbon nanotube forests on piezoelectric AlN films and fabricate and characterize nanotube-based solidly mounted bulk acoustic wave resonators employing the forests as the top electrode material. The devices show values for quality factor at anti-resonance of ?430, and at resonance of ?100. The effective coupling coefficient is of ?6%, and the resonant frequencies are up to ?800 MHz above those observed with metallic top electrodes. AlN promotes a strong catalyst-support interaction, which reduces Fe catalyst mobility, and thus enforces the growth of forests by the base growth mechanism.
