Researchers have revealed groundbreaking research that can potentially alter the field of two-dimensional optoelectronics. Researchers have successfully demonstrated in a groundbreaking study that chicken egg white, i.e., biodegradable albumen, can be a very effective dielectric gate for two-dimensional materials. This breakthrough opens new avenues for sustainable and biodegradable technology in optoelectronic devices. This novel technique was inspired by previous research investigating egg white as a dielectric for organic semiconductors. Some publications already employ egg white as a dielectric for organic semiconductors, so it was just a matter of looking through the literature for ideas. Albumen is easily accessible, inexpensive, and, most importantly, biodegradable. It makes it an appealing alternative to traditional dielectrics, frequently using non-eco-friendly materials.
However, the actual applicability and prospective benefits of employing biodegradable albumen as a gate dielectric in optoelectronic devices distinguish this study. According to the project’s chief researcher, “Egg white has a very high dielectric constant and also works as an ionic conductor, allowing us to achieve very high electron mobilities in our transistors.”
This finding has ramifications for both the performance of optoelectronic devices and their environmental impact. They have fabricated phototransistors with photo response figures of merit that are comparable to the state of the art. Furthermore, the biodegradability of albumen allows for the production of devices with a lesser environmental impact. The fabrication processes can be expanded to any other two-dimensional material, allowing for many other device topologies.
