Abstract
Diamond crystallites up to 40 nm in size have been grown from a highly ionised plasma beam of acetylene for ion energies close to 100 eV per C atom and substrate temperatures above 450 degrees C. This shows tha t diamond can be grown by physical vapour deposition from an ion-rich plasma as well as by chemical vapour deposition from a radical-rich pl asma. The formation mechanism is argued to be one of nucleation and gr owth rather than a stress-induced transformation from graphite. (C) 19 97 Elsevier Science S.A.
