An off-surface visualization method using micro water droplets and a laser beam sheet was developed. The average size of the water droplets generated by the home-style ultrasonic humidifier was about 5-10 μm. This method was pollution-free, eliminated the problem of toxicity, and provided a sufficient density of tracing particles for good visibility. The(More)
The principal interests in this work are energetic-beam control of carbon-film properties and the’ roles of doping and surface morphology in field emission. Carbon films with variable sp3bonding ii-action were deposited on n-type Si substrates by ArF (193 nm) pulsed-laser ablation (PLA) of a pyrolytic graphite target, and by direct metal ion beam deposition(More)
