A PT/MWCNT hybrid nanotube resonator towards to vibrator device

This paper presented a method of adopting Pt/MWCNT nanowire as a vibrator which is used to increase the quality factors of the MWCNT. A platinum nanowire growth was induced via the EBID method from a carbon nanotube (CNT) emitter with a trimelyl cyclopentadienyl platinum (CpPtMe3) precursor. The MWCNT was driven by the electrostatic force on its nature frequency. Two groups of experiments were carried out. We find that the Q value is increased and the resonance frequency was decreased after the growth of high-purity platinum on the tip of a MWCNT. The Q value of the Pt/MWCNT is 20.2 which is larger than the MWCNT without Pt whose Q value is 10.1. For the resonance frequency, the value of the Pt/MWCNT is 57 KHz which is smaller than the MWCNT whose value is 89 KHz.
