Researchers from the University of Surrey have made a breakthrough in solving a problem with source-gated transistors (SGTs), which are low-cost and energy-efficient displays. SGTs have not been widely used due to performance issues with temperature changes. The scientists have developed a new design for the transistor part called the source by adding thin layers of insulating material at the source contact. This modification has made the transistors more stable with temperature. The use of a semiconductor material called IGZO has allowed for the creation of the next generation of SGTs. These transistors retain the benefits of low power usage, high signal amplification, and reliability in different conditions. While SGTs still have limitations, the researchers are gradually addressing these drawbacks. SGTs are a special type of transistor that combines a thin-film transistor and a metal-semiconductor contact, and they offer advantages such as lower power consumption and stability. They have potential applications in fields such as medicine, engineering, and computing. The study has been published in IEEE Transactions on Electron Devices. The University of Surrey focuses on sustainability and is committed to improving resource efficiency and becoming carbon neutral by 2030. They aim to make a difference in the world by conducting research that aligns with the United Nations’ Sustainable Development Goals.
