SU-8 clamped CVD graphene drum resonators
Sunwoo Lee, Changyao Chen, Vikram V. Deshpande +8
Graphene mechanical resonators are the ultimate two-dimensional nanoelectromechanical systems (NEMS) with applications in sensing and signal processing. While initial devices have…
Graphene mechanical oscillators with tunable frequency
Changyao Chen, Sunwoo Lee, Vikram V. Deshpande +4
Oscillators, which produce continuous periodic signals from direct current power, are central to modern communications systems, with versatile applications such as timing reference…
Self-sustained micromechanical oscillator with linear feedback
Changyao Chen, Damián H. Zanette, Jeffrey R. Guest +2
Autonomous oscillators, such as clocks and lasers, produce periodic signals \emph{without} any external frequency reference. In order to sustain stable periodic motions, there need…
Modulation of mechanical resonance by chemical potential oscillation in graphene
Changyao Chen, Vikram V. Deshpande, Mikito Koshino +5
The classical picture of the force on a capacitor assumes a large density of electronic states, such that the electrochemical potential of charges added to the capacitor is given b…
Direct observation of coherent energy transfer in nonlinear micro-mechanical oscillators
Changyao Chen, Damián H. Zanette, David Czaplewski +2
Energy dissipation is an unavoidable phenomenon of physical systems that are directly coupled to an external environmental bath. The ability to engineer the processes responsible f…
