Narrow growth window for stoichiometric, layer-by-layer growth of LaAlO3 thin films using pulsed laser deposition

Layer-by-layer Growth for Pulsed Laser Deposition

Pulsed laser deposition (PLD) is a popular growth method, which has been successfully used for fabricating thin films. Compared to continuous deposition (like molecular beam epitaxy) the pulse intensity can be used as an additional parameter for tuning the growth behavior, so that under certain circumstances PLD improves layer-by-layer growth. We present kinetic Monte-Carlo simulations for PLD ...

Pulsed laser deposition vs. matrix assisted pulsed laser evaporation for growth of biodegradable polymer thin films

Thin films of poly (lactide-co-glycolide) (PLGA), a biodegradable polymer, were deposited on Si wafers by both conventional pulsed laser deposition (PLD) and matrix assisted pulsed laser evaporation (MAPLE) using chloroform (CHCl3) as a matrix solvent. This research represents an initial study to investigate the deposition characteristics of each technique at comparable conditions to gain insig...

Layer-by-layer Pattern Propagtion and Pulsed Laser Deposition

In this article kinetic Monte Carlo simulations for molecular beam epitaxy (MBE) and pulsed laser depositon (PLD) are compared. It will be shown that an optimal pattern conservation during MBE is achieved for a specific ratio of diffusion to deposition rate. Further on pulsed laser deposition is presented as an alternative way to control layer by layer growth. First results concerning the islan...

Pulsed Laser Deposition of Hydroxyapatite Thin Films

Pulsed laser deposition of VO2 thin films

High quality vanadium dioxide ~VO2! thin films have been successfully deposited by pulsed laser deposition without postannealing on ~0001! and ~101̄0! sapphire substrates. X-ray diffraction reveals that the films are highly oriented with ~010! planes parallel to the surface of the substrate. VO2 thin films on ~0001! and ~101̄0! substrates show semiconductor to metal transistions with electrical r...
