The induction of distinctive chemical images in the field-effect devices upon gas exposure by the use of a controlled large area illumination provided by a computer screen was reported. To generate two-dimensional photocurrent images, the concurrent optical and chemical modulation of the semiconductor surface potential of a single metal-oxide-semiconductor capacitor was used. It was concluded that the use of a computer screen as a programmable light source simplifies a normally complex setup.
