Measuring frequency fluctuations in nonlinear nanomechanical resonators
Olivier Maillet, Xin Zhou, Rasul R. Gazizulin +5
Advances in nanomechanics within recent years have demonstrated an always expanding range of devices, from top-down structures to appealing bottom-up MoS and graphene membranes…
Low-power photothermal self-oscillation of bimetallic nanowires
Roberto De Alba, T. S. Abhilash, Richard Rand +2
We investigate the nonlinear mechanics of a bimetallic, optically absorbing SiN-Nb nanowire in the presence of incident laser light and a reflecting Si mirror. Situated in a standi…
Tunable phonon cavity coupling in graphene membranes
R. De Alba, F. Massel, I. R. Storch +5
A major achievement of the past decade has been the realization of macroscopic quantum systems by exploiting interactions between optical cavities and mechanical resonators. In the…
Detection of DNA and Poly-L-Lysine using CVD Graphene-channel FET Biosensors
Aniket Kakatkar, T. S. Abhilash, Roberto De Alba +2
A graphene channel field-effect biosensor is demonstrated for detecting the binding of double-stranded DNA and poly-l-lysine. Sensors consist of CVD graphene transferred using a cl…
Transfer Printing of CVD Graphene FETs on Patterned Substrates
T. S. Abhilash, Roberto De Alba, Nikolay Zhelev +2
We describe a simple and scalable method for the transfer of CVD graphene for the fabrication of field effect transistors. This is a dry process that uses a modified RCA cleaning s…
Evanescent field optical readout of graphene mechanical motion at room temperature
Robin M. Cole, George A. Brawley, Vivek P. Adiga +5
Graphene mechanical resonators have recently attracted considerable attention for use in precision force and mass sensing applications. To date, readout of their oscillatory motion…
Simultaneous Electrical and Optical Readout of Graphene-Coated High Q Silicon Nitride Resonators
V. P. Adiga, R. De Alba, I. R. Storch +8
We have fabricated and tested mechanical resonators consisting of a single-atomic-layer of graphene deposited on suspended silicon nitride membranes. With the addition of the graph…
Stamp transferred suspended graphene mechanical resonators for radio-frequency electrical readout
Xuefeng Song, Mika Oksanen, Mika A. Sillanpää +3
We present a simple micromanipulation technique to transfer suspended graphene flakes onto any substrate and to assemble them with small localized gates into mechanical resonators.…
Synchronous imaging for rapid visualization of complex vibration profiles in electromechanical microresonators
Yoav Linzon, Daniel J. Joe, Slava Krylov +4
Synchronous imaging is used in dynamic space-domain vibration profile studies of capacitively driven, thin n+ doped poly-silicon microbridges oscillating at rf frequencies. Fast an…
Strong gate coupling of high-Q nanomechanical resonators
Jaakko Sulkko, Mika A. Sillanpää, Pasi Häkkinen +5
The detection of mechanical vibrations near the quantum limit is a formidable challenge since the displacement becomes vanishingly small when the number of phonon quanta tends towa…
High-Q Nanomechanics via Destructive Interference of Elastic Waves
I. Wilson-Rae, R. A. Barton, S. S. Verbridge +4
Mechanical dissipation poses an ubiquitous challenge to the performance of nanomechanical devices. Here we analyze the support-induced dissipation of high-stress nanomechanical res…
Tuning mechanical modes and influence of charge screening in nanowire resonators
Hari S. Solanki, Shamashis Sengupta, Sajal Dhara +6
We probe electro-mechanical properties of InAs nanowire (diameter ~ 100 nm) resonators where the suspended nanowire (NW) is also the active channel of a field effect transistor (FE…
