PEDOT:PSS/ZnO nanorods (NRs)/GZO heterojunction UV light detectors with the ZnO NRs layers grown from the CBD solutions with the different concentration ratios of C6H12N4 (HMT) to Zn(NH3)2·6H2O (ZnNit) ([HMT]/[ZnNit]) were fabricated. The [HMT]/[ZnNit] value was changed in the range from 0.24 to 3.78. Values of diode ideal factors (n), rectification ratios (IF/IR) and potential barrier heights at the PEDOT:PSS/ZnO NRs heterointerfaces (Φb) were determined from the voltage-current (V-I) characteristics taken in a dark. The n values smaller than 2 were obtained in the [HMT]/[ZnNit] range from 0.94 to 2.83. Both the IF/IR and Φ_b increased with increasing [HMT]/[ZnNit]. The UV light detector involving the ZnO NRs layer grown from the CBD solution with [HMT]/[ZnNit]=0.94 exhibited the maximum ratio of photocurrent (PC) to dark current of 92.6. PC spectra were composed of bands with peaks at ~360 nm and ~380 nm. The intensity ratio of the 360 nm peak to the 380 nm peak (I360nm/I380nm) exhibited a maximum at [HMT]/[ZnNit]=0.94. The I360nm/I380nm value decreased along with the change in [HMT]/[ZnNit] from 0.94 towards both the lower and higher sides. |
