I would like to buy graphite target for further DLC films creation by PLD technique, does anybody have some good experience with company offering it in terms of reliability and good quality?
You can try using pure high density graphite rods. Available from "American elements" of varying purity and high density. With a rod of 20 to 25 cm diameter, it is easy to cut thin discs (2-3mm) in thickness, and use them as PLD targets. Just see that they are highly dense, and not compacted with any polymeric material.
