Parametric Manipulation in 2D Material based NEMS Resonators

Abstract

In this this thesis, I have studied dynamics of the two-dimensional (2D) material based NEMS resonators with resonant frequency ranging typically from 10 MHz to 100 MHz. The experiment involved fabrication of the suspended nano-scale devices both with global and local gate architectures. The experiments focused on parametric manipulation of MoS2 drum resonator using electrical actuation and detection schemes. This study demonstrated parametric ampli cation in the NEMS at non-cryogenic temperature and discussed effects of During non-linearity on the parametric gain. Further, multimodal coupling among the mechanical modes in the drum resonator was also demonstrated
