Carbon encapsulation of levitated Au nanoparticles
Joyce E. Coppock, Sunghyun Kim, B. E. Kane
We investigate the formation of a barrier to evaporation that develops when levitated nanoscale Au nanoparticles are exposed to pulses of 532 nm laser radiation in a high vacuum (p…
Microfabricated Au and Au/graphene bilayer platelets for levitation experiments
Sunghyun Kim, Joyce E. Coppock, B. E. Kane
We describe a fabrication process for preparing liquid suspensions of micron-scale Au and Au/graphene bilayer platelets using thin-film deposition, optical lithography, ion milling…
Collection, characterization, and precision measurement of levitated charged nanoparticles
B. E. Kane, Joyce Coppock, Sunghyun Kim +1
We describe apparatus and experimental procedures for high stability precision measurements of levitated nanoscale particles confined in an ion trap in high vacuum. We discuss meth…
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…
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…
