Ion beam modification of the structure and properties of hexagonal boron nitride: An infrared and X-ray diffraction study

Aradi, E.; Naidoo, S.R.; Billing, D.G.; Wamwangi, D.; Motochi, I.; Derry, T.E. (Nuclear Instruments and Methods in Physics Research B, 2014-03)

The vibrational mode for the cubic symmetry of boron nitride (BN) has been produced by boron ion implantation of hexagonal boron nitride (h-BN). The optimum fluence at 150 keV was found to be 5 Â 1014 ions/cm2. The ...
Surface Brillouin scattering observation of higher order resonances in annealed, ion-implanted CVD diamond

Motochi, I.; Mathe, B.A.; Naidoo, S.R.; Wamwangi, D.; Derry, T. E. (Science Direct, 2017-06)

The phase velocity of Surface Acoustic waves exhibits no dispersion in homogeneous materials. However, normal or anomalous dispersion takes place in layered systems. This dispersion effect has been used to determine the ...
Surface Brillouin scattering on annealed ion-implanted CVD diamond

Motochi, I.; Naidoo, S.R.; Mathe, B.A.; Erasmus, R.; Aradi, E.; Derry, T.E.; Olivier, E.J. (Diamond & Related Materials 56, 2015-04)

Single crystal b100N diamond samples were implanted with a total fluence of 1.5 × 1016 ions/cm2 at single en- ergy of 150 keV using carbon ions. This implantation fluence created a damage density that would not restore ...
