Figure 2From: Photoinduced oxygen release and persistent photoconductivity in ZnO nanowires Transient photocurrent of the ZnO nanowire in air under UV illumination. The intensity of the λ = 313 nm light is approximately 1.3 mW/cm2. Inset: steady-state photocurrent versus light intensity in air. The bias voltage is 0.3 V and is the same for all other photocurrent measurements.Back to article page
