Nanocrystal Geometry Governs Phase Transformation Pathways in Palladium Hydride
Daewon Lee, Sam Oaks-Leaf, Hyeonjong Ma +14
Pathways and structural dynamics of phase transformations impact performance of materials in energy and information storage technologies. Palladium hydride () nanoc…
Charge Neutral MoS2 Field Effect Transistors Through Oxygen Plasma Treatment
Rohan Dhall, Zhen Li, Ewa Kosmowska +1
Lithographically fabricated MoS2 field effect transistors suffer from several critical imperfections, including low sub-threshold swings, large turn-on gate voltages (VT), and wide…
Scanning gate microscopy of ultra clean carbon nanotube quantum dots
Jiamin Xue, Rohan Dhall, Stephen B. Cronin +1
We perform scanning gate microscopy on individual suspended carbon nanotube quantum dots. The size and position of the quantum dots can be visually identified from the concentric h…
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…
