Step 1

Ambient

hydrogen, methane plasma

Process details

steps:providing a substrate, placing the substrate in a microwave plasma chemical vapor deposition chamber, providing hydrogen gas to the chamber, exposing the substrate to plasma, providing methane gas to the chamber, placing product in an evacuated tube along with potassium metal, heating the metal to produce melting and sublimation such that potassium vapor permeates the tube, maintaining a cold environment near the product such that the potassium condenses on the product, cooling the entire system and removing an intercalated product
