Optoelectronic Circuits Having Controlled Electric Flow (No. 0140)

Summary

A novel optoelectronic circuit that provides controlled electron flow.

Optoelectronics includes devices that either convert light energy to electricity or electricity to light energy. These devices account for a major share in the global semiconductor market and are witnessing growing consumption across various verticals. The classic example of manipulating the distribution of photocarriers is the separation of unlike charges – electrons and holes, via an electric field or energy gradient. This has been the cornerstone of various optoelectronic technologies to date – solar cells, photodetectors, and others. However, being able to manipulate distributions of like photocarriers, say electrons, with high resolution would provide another, perhaps even more powerful, platform for future opto-electronic control. Here we present a promising optoelectronic platform developed by a group of researchers led by Prof. Keshav Dani which provides a better electric flow control.
