But there are still several problems concerning the stability and reproducibility of device fabrication . the heavily born doped p - type diamond films synthesized by hot filament chemical vapor deposition with b ( ch3 ) 3 as boron source substituted the metal electrode aluminum 本文还利用热灯丝化学汽相沉积( hfcvd )法，采用硼酸三甲酯b ( ch3 ) 3为硼源制备了重掺杂p型金刚石膜，作为lppp / alq异质结增强型发光器的电极。
