|Researchers at Purdue University have developed a novel Si-based vacuum transistor for integrated circuits with applications in analog, digital, and memory. These types of transistors can be used in a wide array of applications but are exceptionally suited for high-power high-frequency electronics and electronics used in harsh environments. This technology can also be used in compact 3D logic and memory circuits as well as non-volatile logic where the market is currently limited to semiconductors.
Current technologies such as vacuum microwave tubes have poor reliability and are often bulky and expensive. Additionally, there remains an unmet need for solutions in high temperature, high radiation environments. However, Purdue researchers have implemented nanoscale field emitter array (FEA) vacuum transistors made from Si-based materials that are reliable and suitable for environments up to 300 degrees C and have ability to operate under sustained high radiation without exhibiting signs of mechanical failure. The new transistors also ensure data storage in the event of a sudden shut down of power supply, unlike traditional systems.
