Effects of plasmon resonance on the low frequency noise and optoelectronic properties of Au/Cu codoped ZnO based photodetectors

چکیده
We have investigated the effect of Au nanoparticles on low frequency noise and current-voltage Au/Cu doped ZnO (Nps) based photodetectors (PDs). Besides, 1/f Cu is studied with without Nps conditions varied bias voltages. The codoped showed much lower higher normalized photocurrent to dark current ratio (NPDR) than undoped Nps. This enhancement may be attributed localized surface Plasmon resonances (LSPR). Furthermore, equivalent power represents minimum optical that a photodetector can distinguish from detectivity (D*) an important parameter in evaluating ability detect weak signal. These parameters were determined using measurements. observed performances could used for UV photodetectors.
