Pulsed Laser Deposition

Previously, I wrote about different ways to make graphene. This time, I will write about a physical way to make graphene from a bulk of graphite. The name of the method is "Pulsed Laser Deposition."As the picture shows, it shoots a laser beam on the graphite. The bulk of graphite receives energy from laser, and the atoms separate transforming itself into plasma. The plasma gets accumulated on the substrate which is made of copper. The copper was previously shown to be the most efficient substrate for the CVD method, and it led to the PLD substrate as well. Important thing to remember is that the substrate has to be heated up to a high temperature.
