Study: an ingredient in coffee can make semiconductors run faster
CTOnews.com, December 11 (Xinhua)-- according to a study by Japan's Advanced Industrial Science and Technology (AIST) Research Institute, an ingredient found naturally in coffee may make semiconductors run faster.
The researchers say the use of coffee compounds can increase the current in semiconductor devices by as much as 100 times. Specifically, according to their work, a thin layer of caffeic acid on the surface of the electrode promotes a great improvement in current in organic semiconductor devices.
Figure source Pexels according to the study, after a thin layer of caffeic acid is formed on the surface of the electrode, caffeic acid molecules are spontaneously arranged in a row on the surface of the electrode, speeding up the current flow rate. While that doesn't mean you can increase the speed of your computer by spilling coffee on it, Japanese researchers believe the breakthrough may have some practical applications, including the development of fully sustainable organic semiconductor devices that could be made entirely from biomass-derived materials.
CTOnews.com learned that although organic semiconductors already exist, such as organic light-emitting diodes (OLED) and organic solar cells (OPV), the researchers point to the environmental impact of dealing with these technologies. The researchers point out that the electrode modification layer currently used is used to accelerate the flow of charge in semiconductors, and the use of these materials "may have adverse effects on aquatic organisms."
According to the researchers, the use of caffeic acid, which can be extracted entirely from plants, can reduce the need to use unsustainable chemicals in semiconductor production. AIST researchers hope to apply this electrode modification / coating technology to these organic semiconductor devices such as OLED and OPV, with the ultimate goal of making semiconductor components and Internet of things devices fully sustainable and easy to recycle.
