- Fig. 5 (A) when one of the electrodes, ITO, which is a metal oxide on ITO, is irradiated with ultraviolet light, electrons in the valence band of tin dioxide are conducted. Excited by the band. In the vicinity of the interface with ITO, this electron passes through the insulator with a certain probability and is temporarily trapped in ITO, and the interatomic distance at the site where the electron in the valence band has escaped changes. The trapped electrons return to the valence band of tin dioxide again. The level at this time moves into the band gap as shown in Fig. 5 (B). Such an event occurs repeatedly, and many levels are formed in the band gap as shown in Fig.
- the role of the insulator is to create a barrier between ITO and tin dioxide and allow the excited electrons to pass. Tin dioxide undergoes a structural change when it is exposed to ultraviolet radiation with an insulator between ITO and tin dioxide.
- the transmittance value in a state where decoloring has occurred is large, it is possible to realize a reflective display device with high contrast and a bright background. Since the main component of the electric field sensitive element 1 is a solid, damage due to mechanical impact is less likely to occur compared to a configuration in which all liquids or liquids are contained. Since the structure is simple, it is advantageous for low cost.
