R. Kapil et al., SYNTHESIS OF 15R POLYTYPE OF DIAMOND IN OXY-ACETYLENE FLAME GROWN DIAMOND THIN-FILMS, Applied physics letters, 68(18), 1996, pp. 2520-2522
15R polytype of diamond has been synthesized using a specially designe
d oxy-acetylene flame system along with 3C diamond and cubic carbon on
polycrystalline molybdenum substrates. X-ray diffraction has been use
d to detect the 15R phase as the dominant phase in these films. Rapid
changes in the substrate temperature during the growth process are exp
ected to be responsible for the growth of these phases. (C) 1996 Ameri
