A New Innovation Paves the Way for Low-Cost, Energy-Efficient Displays

ow-Cost, Energy-Efficient Displays

Low-cost, energy-efficient displays that consume minimal power are on the horizon, thanks to a groundbreaking innovation from the University of Surrey. Researchers at the university have addressed a significant obstacle faced by source-gated transistors (SGT), bringing these promising devices closer to widespread use. By introducing a novel design for the transistor’s source component, scientists have overcome temperature-related performance challenges that have hindered the adoption of SGTs in the past.

Solving Temperature-Related Performance Issues

Traditional source-gated transistors have faced limitations due to their performance fluctuations with temperature. However, researchers at the University of Surrey have devised a solution. By incorporating ultra-thin layers of insulating material at the source contact, they have successfully altered the flow of electric charges. This innovative approach utilizing the semiconductor material IGZO (indium-gallium-zinc oxide) has yielded a new generation of source-gated transistors that exhibit remarkable stability across varying temperatures. Detailed device simulations have provided valuable insights into this improved performance.

Enhanced Benefits and Potential Applications

The novel design not only addresses the temperature stability issue but also retains the inherent advantages of source-gated transistors. These benefits include low power consumption, high signal amplification, and increased reliability under diverse conditions. While SGTs have not yet gained mainstream adoption due to a few performance limitations, this research is gradually overcoming these hurdles, opening doors to their wider utilization.

Source-gated transistors, which combine thin-film transistors with meticulously engineered metal-semiconductor contacts, offer several advantages over conventional transistors. These include reduced power usage and improved stability. Given their suitability for large-area electronics, SGTs hold great promise in fields such as medicine, engineering, and computing. Their sensing capabilities and signal amplification potential make them ideal for medical devices that interface with the human body, enabling a deeper understanding of human health.

Acknowledging the Researchers’ Contributions

The simulations pivotal to this breakthrough were conducted by Salman Alfarisyi as part of his final-year undergraduate project at the University of Surrey. Salman emphasizes that source-gated transistors could serve as the foundation for new energy-efficient flexible electronics technology, playing a crucial role in meeting our energy demands while prioritizing environmental sustainability. These advancements could have far-reaching implications, particularly in developing medical devices and promoting overall well-being.


The pioneering research conducted at the University of Surrey, published in the prestigious IEEE Transactions on Electron Devices, has propelled source-gated transistors closer to becoming the go-to solution for low-cost, energy-efficient displays. By addressing temperature-related performance challenges, the innovative design demonstrates enhanced stability while preserving the inherent benefits of SGTs. The University of Surrey’s commitment to sustainability and impactful research reinforces its standing as a global leader in tackling climate change and promoting a more sustainable future.
