Nanoscale electromechanical resonators as probes of the charge density wave transition in NbSe
Shamashis Sengupta, Hari S. Solanki, Vibhor Singh +2
We study nanoelectromechanical resonators fabricated from suspended flakes of NbSe (thickness30-50 nm) to probe charge density wave (CDW) physics at nanoscale. Variation…
Probing thermal expansion of graphene and modal dispersion at low-temperature using graphene NEMS resonators
Vibhor Singh, Shamashis Sengupta, Hari S. Solanki +5
We use suspended graphene electromechanical resonators to study the variation of resonant frequency as a function of temperature. Measuring the change in frequency resulting from a…
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…
