*Abstract: Researchers at the University of California, Berkeley have developed highly sensitive ultraviolet light sensors based on zinc oxide nanowires. Upon exposure to light of wavelength below 400 nm, the electrical resistivity of the semiconducting nanowires decreases by 4-5 orders of magnitude.
