Scientists in China, South Korea devise ‘pioneering strategy’ for breakthrough in semiconductor technology
Newly devised strategy could make commercially viable amorphous p-type semiconductors a reality, team in Chengdu and Pohang says in Nature paper.
Complementary metal-oxide semiconductor (CMOS) technology, which is widely used to make memory chips and computer processors, helps to produce reliable integrated circuits that require low inputs of power. However the traditional amorphous hydrogenated silicon used in such applications “falls short in electrical properties, necessitating the exploration of new materials”, they wrote in a paper published as an accelerated preview in the peer-reviewed journal Nature on Wednesday. The development of “thin-film transistors”, the technology that led to liquid crystal screen displays, has been propelled forward by the creation of high-mobility amorphous n-type semiconductors, the team said.
