Abstract
In this work, further ion-beam was performed on SiO2-matrix B-doped Si-NC (SBC) thin films in order to enhance conductivity. The effect of ionbeam type on the electrical properties of SBC thin films was investigated systematically. The results indicated that the conductivities of SBC thin films were significantly improved by both argon and hydrogen ion-beam treatments, and the higher the hydrogen ion ratio, the higher the conductivity of SBC thin films. The conductivity of SBC thin films was increased from 1.82 × 10−6 S/cm to 3.2 × 10−3 S/cm with following hydrogen-ion-beam treatment. The change in conductivity of SBC thin films was most possibly resultant from the ion-beam treatment facilitating the formation of higher superficial order and lower defects. An alternative method was proposed to prepare high-conductivity SBC thin films, which may be applied to other heterogeneous thin films.
