    Implantation of Ti into Oxides for Optical Applications
    (Addis Ababa University, 1995-06) Thomas, Petros
    Titanium (Tt2) implantation and annealing of lithium niobate (LiNbOJ) and sapphire (AI,OJ) has been investigated using RES and SIMS measurements. The implantation was done at room temperature with doses- IOI5Ti/cm2, IOHTi/cm2, 5xl01"Ti/cm2 and I017Ti/cm'. The energy of implantation was 400 ke V. After implantation the samples were annealed with oven (10600C for one hour) and rapid thermal annealer (10600C for one minute).
