Light incident angle controllable electronic device and manufacturing method thereof

Abstract

Disclosed herein is a method of changing characteristics of an electronic device, including the steps of: applying light to an electronic device through a plurality of media having different refractive indexes from each other, the electrical characteristics of the electronic device being changed depending on the amount of incident light; and changing an incident angle of light applied the electronic device to adjust the amount of incident light. There is provided a method of providing light incident angle dependency by a simple procedure of accumulating additional media in various electronic devices. In the method, the light incident angle selectivity of the electronic device can be maintained even when the inclination angle of the device is changed depending on the axis parallel to the incident direction of light even though the incident direction thereof is fixed. This means that the performance of the device can be controlled only by changing the inclination angle of the device without greatly changing the dynamic state of the device. Further, since the movement speed of photons is higher than that of electrons and the signal interference of photons is lower than that of electrons, an additional effect of increasing the operating speed of the device or decreasing the size of the device can be expected.
