Engineering Surface Oxygen Vacancies in to Form a High Mobility and Transparent Quasi Two dimensional Electron System
Shyam Sundar Yadav, Shelender Kumar, Pankaj Kumar +1
Quasi-two-dimensional electron systems (q-2DES) are formed in various hetero-structures, including oxide interfaces. Oxygen vacancies (OVs) in oxides like are kn…
Temperature Dependent Non-linear Damping in Palladium Nano-mechanical Resonators
Shelender Kumar, S. Rebari, Satyendra P. Pal +5
Advances in nano-fabrication techniques has made it feasible to observe damping phenomena beyond the linear regime in nano-mechanical systems. In this work, we report cubic non-lin…
Low temperature dissipation scenarios in palladium nano-mechanical resonators
S. Rebari, Shelender Kumar, S. Indrajeet +4
We study dissipation in Pd nano-mechanical resonators at low temperatures in the linear response regime. Metallic resonators have shown characteristic features of dissipation due t…
Nonlinear modal coupling in a high-stress doubly-clamped nanomechanical resonator
K. J. Lulla, R. B. Cousins, A. Venkatesan +4
We present results from a study of the nonlinear intermodal coupling between different flexural vibrational modes of a single high-stress, doubly-clamped silicon nitride nanomechan…
Dissipation due to tunneling two-level systems in gold nanomechanical resonators
A. Venkatesan, K. J. Lulla, M. J. Patton +3
We present measurements of the dissipation and frequency shift in nanomechanical gold resonators at temperatures down to 10 mK. The resonators were fabricated as doubly-clamped bea…
