Abstract

For the secondary electron emission studies a series of poly- and nano-crystalline diamond films with different characteristics (crystallinity, morphology and dopants) were produced using an innovative CVD apparatus that allows the doping of diamond layers. Moreover additional hydrogenation processes were carried out after the first emission experiments in order to obtain H termination at three diamond surface and enhance the electron yield. At 1 KeV a gain of 5.5 has been obtained for Ti-doped diamond layers and for diamond layers containing C-sp² clusters.
