Tension mediated nonlinear coupling between orthogonal mechanical modes of nanowire resonators
John P. Mathew, Anand Bhushan, Mandar M. Deshmukh
We study the nonlinear coupling between orthogonal flexural modes of doubly clamped InAs nanowire resonators. The two orthogonal modes are formed by the symmetry breaking and lifti…
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…
Dynamical strong coupling and parametric amplification in mechanical modes of graphene drums
John P. Mathew, Raj N. Patel, Abhinandan Borah +2
Mechanical resonators are ubiquitous in modern information technology. With the ability to couple them to electromagnetic and plasmonic modes, they hold the promise to be the key b…
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…
Carrier Transport in High Mobility InAs Nanowire Junctionless Transistors
Aniruddha Konar, John Mathew, Kaushik. Nayak +5
Ability to understand and model the performance limits of nanowire transistors is the key to design of next generation devices. Here, we report studies on high-mobility junction-le…
Limits on the Bolometric response of Graphene due to flicker noise
Sameer Grover, Sudipta Dubey, John P. Mathew +1
We study the photoresponse of graphene field effect transistors using scanning photocurrent microscopy in near and far field configurations, and we find that the response of graphe…
