The consensus seems to be that this is only a laboratory result and would take years to reproducible at scale. >Bi₂O₂Se, or bismuth oxyselenide, is a semiconductor material studied for its use in sub-1nm process nodes for years, largely thanks to its ability to be a 2D semiconductor. Two-dimensional semiconductors, like 2D Bi₂O₂Se, are more flexible and sturdy at a small scale than silicon, which runs into reduced carrier mobility at even the 10nm node. >Thanks to a U.S.-China trade war over chips and modern technology, China finds itself cut off from tools like EUV lithography that enable the production of processors on nodes that the rest of the tech world has been producing for nearly a decade. As a result, China has invested heavily in research that will allow it to leapfrog the current state of the tech industry, ***** https://slashdot.org/story/441655 South China Morning Post https://archive.ph/lqZIi
