Low-Frequency Noise Spectra of Laterally Bridged ZnO Microrod-Based Photodetectors

The laterally bridged ZnO microrods grown from an Au electrode applied to metal-semiconductor-metal photodetector was fabricated. Interlaced ZnO microrods with approximate single-crystalline structure can be grown from Au electrode fingers. The dark-current was 5.00 × 10-5 A with an applied voltage of 1 V. Highly dense lateral ZnO microrod-based photodetectors produce remarkable responsivity of 1....
