Nano Films for On-Chip Energy Storage

Did you know that tiny molecular layers can be grown and used as teeny-tiny energy storage devices on a chip? Scientists have found a way to create these using benzimidazole compounds. They laid these layers on a special surface withelectrochemical methods, creating films as thin as 10 nanometers. Interestingly, the thinner the film, the more energy it can store, due to something called a dielectric role. The film acts like a tiny capacitor, stowing energy away. Electrical tests and computer models showed that these molecular junctions could store a lot of energy, peaking at about 53 microfarads per square centimeter when the film was only 10 nanometers thick. To check how well they worked over time, scientists even tested these junctions with alternating current. The bottom line? These tiny films could be the building blocks for future, energy-saving nanoscale devices.
