Pulsed Laser Deposition

 

Pulsed laser deposition (PLD) is a deposition process using high power pulsed laser to ablate material for a target which is then deposited onto a substrate.  In this project a standard PLD setup as depicted here was used for characterizing the process then a for deposition inside quartz tubes was developed.  PLD can be used to deposit a wide range of materials from polymers to metals.  A couple of unique characteristics are the deposited particles high kinetic energy (~100 eV) and the wide deposition temperature range (0-1000 C).  Films made PLD can be extremely smooth and amorphous, or crystalline depending on the chamber atmosphere.
