Crystal Growth Kinetics of Boron Oxide Under Pressure
(American Institute of Physics, 1985)We have measured the crystal growth rate u of B2O3-I in the amorphous phase, as it varied over five orders of magnitude with changes in temperature and pressure. We eliminated the crystal nucleation barrier by seeding the ... -
Effect of deposition rate on morphology evolution of metal-on-insulator films grown by pulsed laser deposition
(American Physical Society, 2007)Ag films were grown by pulsed laser deposition on insulating SiO2 and mica substrates and exhibited a morphological progression beginning with nucleation of three-dimensional islands and culminating in a continuous, ... -
Pulsed Excimer (KrF) Laser Melting of Amorphous and Crystalline Silicon Layers
(American Institute of Physics, 1985)We have investigated depth of melting as a function of pulse energy density in amorphous and crystalline silicon layers. The melting threshold for KrF laser pulses (lambda=0.249 µm, tau=24×10−9 s) in amorphous (7660-Å-thick) ...
