The A-B transition in superfluid 3He under confinement in a thin slab geometry
N. Zhelev, T. S. Abhilash, E. N. Smith +5
The influence of confinement on the topological phases of superfluid 3He is studied using the torsional pendulum method. We focus on the phase transition between the chiral A-phase…
Nanoscale electromechanics to measure thermal conductivity, expansion and interfacial losses
John P. Mathew, Raj Patel, Abhinandan Borah +3
We study the effect of localized Joule heating on the mechanical properties of doubly clamped nanowires under tensile stress. Local heating results in systematic variation of the r…
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…
Wide bandwidth nanowire electromechanics on insulating substrates at room temperature
T. S. Abhilash, John P Mathew, Shamashis Sengupta +3
We study InAs nanowire resonators fabricated on sapphire substrate with a local gate configuration. The key advantage of using an insulating sapphire substrate is that it results i…
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…
