| We present ZnO nanorod/ZnO thin film structures synthesized at different molarities and growth times using a hydrothermal method, exhibiting uniquely solar sensing characteristics. ZnO thin film was deposited on p-Si(100) substrate by using RF sputter. ZnO nanorods with different molarities (10 and 20 mM) and growth times (2, 3, and 4 h) were fabricated at 90 °C by using the hydrothermal method on the n-ZnO/p-Si. The surface texture was also examined by scanning electron microscopy. The diameter of ZnO NRs was in the range of 62--119 nm. The current--time measurements were done under solar light illumination intensity (50 and 100 mW/cm2) and forward bias voltage (1, 5, and 10 V). Decay time (τd), rise time (τr), detectivity (D*), responsivity (R), and sensitivity (S) parameters were calculated. Samples produced at 2 h and 3 h in 10 mM solution performed best due to low τd, τr, and high D*, R, S. Especially, the S for the PD102 changed from 4.24 to 11.8, while it was in the range of 0.41--7.33 for the PD103. The R was 5.81 AW−1 in PD102 and 1.19 AW−1 in PD103. The D* was 109--1011 cmHz1/2/W in PD102 and 1010--1011 cmHz1/2/W in PD103 at ± 6 V. |
