O102300100015 SAMPLE Samples consisting of glass carbon which had been O102300100016 implanted with Ta at energy 30-KeV with a fluence of O102300100017 5*10E+16 ions/cm**2 and then with N-14 at energy O102300100018 10-KeV with the same fluence were used. O102300100019 The implantation of tantal ions was done first because O102300100020 of their higher sputtering yield.
