Ionimplantation can surely improve the joining ability of the ceramic surface, but the reasons of improving the brazing ability other than the electric conductivity should be found.
离子注入确实可以显著提高陶瓷材料的可焊性，但提高陶瓷材料表面导电性并不是提高其钎焊性能的主要因素。

Waveguides formed by heavy ions implantation show an unique advantages: the beam dose can be 1-3 order lower than that of light ionimplantation and it can reduce the fabrication cost significantly.
