Optical and Electrical Properties of Si/NiO Heterojunctions with and Without Na or Cu Doping
The Si/NiO heterojunctions with and without Na or Cu doping were prepared by the magnetron sputtering method. The best rectifying characteristics appears in the Si/NiO:Na heterojunction
where the average optical transmittance can reach to 70% in the visible range
which may be explained by the reduced defects due to the improved crystallization. The fitted
I-V
curve of Si/NiO:Na heterojunction indicates that the interface state also affects the rectifying property. Good rectifying property hasn't been observed in Si/NiO and Si/NiO:Cu heterojunctions because of the appearance of more defects. These results are also evidenced by XRD
SEM
AFM and UV results.
