  • Phase Transitions in a Dusty Plasma with Two Distinct Particle Sizes 

    Smith, Bernard; Hyde, Truell; Matthews, Lorin; Reay, Jerry; Cook, Mike; Schmoke, Jimmy (Advances in Space Research, 2008)
    In semiconductor manufacturing, contamination due to particulates significantly decreases the yield and quality of device fabrication, therefore increasing the cost of production. Dust particle clouds can be found in almost ...
  • Probing the sheath electric field using thermophoresis in dusty plasma 

    Land, Victor; Smith, Bernie; Matthews, Lorin; Hyde, Truell (IEEE Transactions on Plasma Science, 2010-04)
    A self-consistent dusty plasma fluid model has been extended to incorporate all the oble gases as the carrier gas. An analysis of void closure in complex plasma composed of these gases over a wide range of experimental ...
  • Simple method to measure the interaction potential of dielectric grains in a dusty plasma 

    Zhang, Zhuanhao; Qiao, Ke; Kong, Jie; Matthews, Lorin; Hyde, Truell (Physics Review E, 2010-09)
    A simple minimally perturbative method is introduced which provides the ability to experimentally measure both the radial confining potential and the interaction potential between two individual dust particles, levitated ...
  • Slow Plastic Deformation (Creep) of 2D Dusty Plasma Solids 

    Hartmann, P.; Kovacs, A. Z.; Douglass, A. M.; Carmona-Reyes, J.; Matthews, L. S.; Hyde, T. W. (Physical Review Letters, 201-07-09)
    We report complex plasma experiments, assisted by numerical simulations, providing an alternative qualitative link between the macroscopic response of polycrystalline solid matter to small shearing forces and the possible ...
  • Two-dimensional and three-dimensional Coulomb clusters in parabolic traps 

    Myasnikov, M.; D'yachkov, L.; Petrov, O.; Hyde, T. W.; Kong., J.; Matthews, L. S. (AIP Publishing, 2014-09-08)
    We consider the shell structure of Coulomb clusters in an axially symmetric parabolic trap exhibiting a confining potential U_c(ρ,z)=(mω^2/2)(ρ^2+αz^2) . Assuming an anisotropic parameter α = 4 (corresponding to experiments ...
  • Vertical Interaction Between Dust Particles Confined in a Glass Box in a Complex Plasma 

    Kong, Jie; Qiao, Ke; Carmona-Reyes, Jorge; Douglass, Angela; Zhang, Zhuanhao; Matthews, Lorin; Hyde, Truell (IEEE Transactions on Plasma Science, 2013-04)
    In this experiment, falling particle trajectories within and without a glass box placed on the lower electrode in a Gaseous Electronics Conference reference cell are recorded and analyzed, and the electrostatic forces ...
  • Vertical probe-induced asymmetric dust oscillation in complex plasma 

    Harris, B. J.; Matthews, L.S.; Hyde, T. W. (Physical Review E, 2013-05-24)
    A complex plasma vertical oscillation experiment which modifies the bulk is presented. Spherical, micron-sized particles within a Coulomb crystal levitated in the sheath above the powered lower electrode in a GEC reference ...
