Abstract

We reported the characteristics of p-type tin-oxide (SnO) thin film transistors (TFTs) upon illumination with visible light. Our p-type TFT device using the SnO film as the active channel layer exhibits high sensitivity toward the blue-light with a high light/dark read current ratio (Ilight/Idark) of 8.2 × 103 at a very low driven voltage of <3 V. Since sensing of blue-light radiation is very critical to our eyes, the proposed p-type SnO TFTs with high sensitivity toward the blue-light show great potential for future blue-light detection applications. (Figure presented.).
