Description
Summary:Structural color emerges from the interaction of light with structured matter when its dimension is comparable to the incident wavelength. The reflected color can be switched by controlling such interaction with materials whose properties can be changed through external stimuli such as electrical, optical, or thermal excitation. In this research, a molybdenum oxide (MoO<sub>x</sub>) reflective grating to get a switchable <i>on</i>/<i>off</i> subpixel is designed and analyzed. The design is based on subpixel <i>on</i> and <i>off</i> states that could be controlled through the oxidation degree of MoO<sub>x</sub>. A suitable combination of three of these subpixels, optimized to get a control of primary colors, red, green, and blue, can lead to a pixel which can cover a wide range of colors in the color space for reflective display applications.
