[摘要]:Electrical passivation induced by a silicon carbide coating deposited on mono-crystalline silicon substrate was investigated by means of photo-conductivity measurements. Roles of the fixed charges and surface defects were compared with silicon nitride coating. The passivation mechanisms were found to be the same as for silicon nitride but a smaller number of fixed charges in the range of the silicon oxide was calculated.
