Researchers have made germanium superconducting for the first time, a feat that could transform computing and quantum technologies. Using molecular beam epitaxy to embed gallium atoms precisely, the ...

Sometimes, a technique or technology that initiates a radical or dramatic advance is soon itself overtaken by a variation or improvement on that initial innovation, with an excellent example being ...

Our current chip technology is largely based on silicon -- even though different materials such as silicon-germanium would have decisive advantages. The problem is that it is very hard to create clean ...

Josephson junction structures—quantum devices made of two superconductors and a thin non-superconducting barrier—using different forms of germanium (Ge): super-Ge (in gold), semiconducting Ge (in blue ...

The integration of silicon‐germanium technology in photonic devices has transformed optoelectronics, enabling the realisation of high‐speed, high‐sensitivity detectors that are central to modern ...
