George, T.; Foote, M. C.; Vasquez, R. P.; Fortier, E. P.; Posthill, J. B., 1993, "Below Band-Gap Laser Ablation of Diamond for Transmission Electron Microscopy", https://hdl.handle.net/2014/35039, Applied Physics Letters, JPL Open Repository
A 248-nm excimer laser was used to thin naturally occurring type 1a diamond substrates at normal and glancing (22 deg) incidence. Perforation of a 250 micron thick substrate was achieved in about 15 minutes at normal incidence. Whilst the substrate thinned at glancing incidence w... |

Lin, T.; Park, J. S.; Gunapala. S. D.; Jones, E. W.; del Castillo, H. M., 1993, "Tailorable Doping-Spike PtSi Infrared Detectors Fabricated by Si Molecular Beam Epitaxy", https://hdl.handle.net/2014/36017, ['1993 International Conference on Solid State Devices and Materials', 'Chiba, Japan', 'Japan Journal of Applied Physics'], JPL Open Repository
By incorporating a 1-nm-thick p+ doping spike at the PtSi/Si interface, we have successfullydemonstrated extended cutoff wavelengths of PtSi Schottky infrared detectors. The extended cutoffwavelengths resulted from the reduced effective potential barriers due to the combined effe... |

Johnson, T. V.; Matson, D. L.; Veeder, G. J.; Blaney, D. L.; Goguen, J. D., 1993, "Implication of the January 1990 Volcanic Eruption on Io for Resurfacing Rates and Energetics", https://hdl.handle.net/2014/36446, ['American Geophysical Union, Fall Meeting', 'San Francisco, CA'], JPL Open Repository
The high temperature event observed by ground based infrared radiometry of Io in January of 1990 can be modeled as an extremely active silicate lava flow which increased its area and cooled over a period of three hours. The best model at the start of the observations is a thermal... |
