I use fundamentally non-equilibrium pulsed laser deposition and pulsed laser annealing processes for the formation of nov el quenched solid phase of carbon (Q-carbon) at room temperature and atmo spheric pressure for electron field-emission device applications. The dev ices have shown excellent electric field enhancement\, very low turn-on e lectric fields and high emission current densities over long periods with tremendous stability even at high temperatures. In this seminar\, I will discuss the direct conversion of crystalline carbon nanotube (CNT) and a morphous carbon structures into nanostructured diamond by nanosecond puls ed laser annealing. The laser-irradiated CNT structures with nanodiamond seeds were used to grow large diamond crystals and hollow conductive diam ond tubes in hot filament chemical vapor deposition.\n\n\nSee full abstra ct here.
