Figure 2. Photoconductivity measurements under white light illumination.

Figure 2

(a) Current-voltage response of a representative device. The black curve represents the dark conditions i.e. the light off state. The green curve shows I–V data when halogen light was made ON and the blue curve represents the same for a particular wavelength of 400 nm. (b) Spectral dependent photoconductivity measurements for wavelengths 400, 500, 550 and 600 nm, at constant bias 500 mV. The labels “ON” and “OFF” represent the light on and off states, respectively. (c) The bias voltage dependent photoconductivity measurements performed at 50, 200, 400 and 500 mV in presence of halogen lamp.
