Color-selective Schottky Barrier Modulation for Optoelectric Logic |
| 초록 |
The limitation on signal processes implementable using conventional circuits based on necessitates revolutionary change in device structures such that they can exploit photons or light. Herein, we introduce optoelectric logic circuits converting optical signals with different wavelengths colors into electric signals. Such circuits are assembled using unit devices in which electric current through channel is gated by lights of different colors. Color-selective optical modulation of the device is achieved using graphene decorated with different organic dyes as the electrode of Schottky diode. The drastic change in electrode work function under illumination induces a change in the height of Schottky barrier formed at the electrode/semiconductor junction and consequent modulation of current; we term the developed device a photonic barristor. We construct logic circuits using array of photonic barristors executing the functions of conventional NAND and NOR gates from optical input signals. |
