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…
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…
