This paper addresses the effects of ambient exposure of a polycrystalline Au electrode prior to making contact with the hole-transport material N,N 0-diphenyl-N,N 0-bis (1-naphthyl)-1,1 0-biphenyl-4,4 0-diamine (a-NPD). Ultraviolet photoemission spectroscopy (UPS) and current–voltage (I–V) measurements are used to investigate the resulting hole barrier and(More)

Abstract The perturbation due to the introduction of a bundle divertor into a tokamak system may induce er-godicity of the magnetic flux surfaces, enhance the(More)
Experiments have recently been conducted at the National Ignition Facility utilizing inertial confinement fusion capsule ablators that are 175 and 165  μm in thickness, 10% and 15% thinner, respectively, than the nominal thickness capsule used throughout the high foot and most of the National Ignition Campaign. These three-shock, high-adiabat, high-foot(More)
We report on the first layered deuterium-tritium (DT) capsule implosions indirectly driven by a "high-foot" laser pulse that were fielded in depleted uranium hohlraums at the National Ignition Facility. Recently, high-foot implosions have demonstrated improved resistance to ablation-front Rayleigh-Taylor instability induced mixing of ablator material into(More)
In digital holography (Kreis, 2005; Schnars & Jueptner, 2005), holograms are recorded using an image sensor such as CCD cameras, and reconstruction of images of the object is performed by a computer. From this, digital holography has following attractive features: A wet process for developing recording media is not required; qualitative evaluation is easy(More)
