Electronics Near Zero
Researchers at King Abdullah University of Science and Technology are exploring gallium oxide as a semiconductor capable of operating in extremely cold environments, such as those near absolute zero. They developed two electronic devices using β-Ga2O3 doped with silicon, which functioned reliably down to 2K. This material's resistance to electron freeze-out and its performance at both high and low temperatures make it promising for applications in quantum computing and deep space electronics.

Electronics Near Zero No comments by: Al Williams April 30, 2026 Title: Copy Short Link: Copy Normally, when you design an electronic gadget, you worry about how hot it will get. Automotive-grade components, for example, often have higher allowable temperatures than commercial parts. However, extremely cold environments, such as deep space or the interiors of quantum computers, are also challenging. Researchers at King Abdullah University of Science and Technology believe gallium oxide may be key to operating near absolute zero. According to [Vishal Khandelwal], one of the researchers, most conventional electronics fail below -173C or 100K. Quantum computers routinely operate at 4K.
