Focused deposition of levitated nanoscale Au droplets
Joyce E. Coppock, B. E. Kane
We describe a method for depositing nanoscale liquid Au droplets, initially levitated in an ion trap in high vacuum, onto a remote substrate. A levitated Au nanosphere is melted, e…
Observation of undercooling in a levitated nanoscale liquid Au droplet
Joyce Coppock, Quinn Waxter, Robert Wolle +1
We investigate melting and undercooling in nanoscale (radius ~100 nm) gold particles that are levitated in a quadrupole ion (Paul) trap in a high vacuum environment. The particle i…
A dual-trap system for the study of charged rotating graphene nanoplatelets in high vacuum
Joyce E. Coppock, Pavel Nagornykh, Jacob P. J. Murphy +3
We discuss the design and implementation of a system for generating charged multilayer graphene nanoplatelets and introducing a nanoplatelet into a quadrupole ion trap in high vacu…
Optical and magnetic measurements of gyroscopically stabilized graphene nanoplatelets levitated in an ion trap
Pavel Nagornykh, Joyce E. Coppock, Jacob P. J. Murphy +1
Using optical measurements, we demonstrate that the rotation of micron-scale graphene nanoplatelets levitated in a quadrupole ion trap in high vacuum can be frequency locked to an…
Cooling of Levitated Graphene Nanoplatelets in High Vacuum
Pavel Nagornykh, Joyce E. Coppock, B. E. Kane
We demonstrate cooling of the center of mass motion of charged graphene nanoplatelets levitated in a quadrupole ion trap in high vacuum down to temperatures of 20 K. Parametric fee…
Strongly metallic electron and hole 2D transport in an ambipolar Si-vacuum field effect transistor
Binhui Hu, M. M. Yazdanpanah, B. E. Kane +2
We report experiment and theory on an ambipolar gate-controlled Si-vacuum field effect transistor (FET) where we study electron and hole (low-temperature 2D) transport in the same…
