Researchers at Lund University have developed new configurable transistors that can exert control at a more precise level, enabling the creation of small, energy-efficient circuits for improved memory and more powerful computers. As traditional transistors reach their size limits, reconfigurable transistors become crucial for enhancing computational power. These transistors allow properties to be changed after manufacturing, unlike standard semiconductors. By using ferroelectric materials that change their polarisation when exposed to an electric field, the researchers created ferroelectric "grains" that control a tunnel junction within the transistor. This research opens the door to creating neuromorphic circuits and advanced applications in various fields such as memory cells, wireless communication, and quantum computing.
