Stanford University (USA) has developed a technology for producing atomically thin, flexible transistors smaller than 100 nm. The new technology, according to the publication Nature Electronics, opens up incredible opportunities in the field of “flexotronics”.
Flexotronics – flexible electronics based on energy-efficient circuits, and is designed to create wearable or implantable devices. Scientists have already created two-dimensional semiconductors, which are much better suited for creating such systems than the usual silicon components.
The main technical problem hindering the development of flexotronics is the destruction of flexible substrates during the complex manufacturing process. The substrates simply melt when exposed to the high temperatures that are created in the manufacturing process. To solve this problem, Stanford scientists proposed an interesting know-how.
The engineers added additional technological steps to the production process, and also used a special inflexible substance as a substrate. Ultimately, the scientists created a technology that makes it possible to obtain a flexible film three atoms thick – many times thinner than a human hair. Such material withstands 850 degrees Celsius, which is enough to ensure that the film will not collapse during the industrial creation of wearable and implantable flexible devices.
