由俄罗斯远东联邦大学、俄罗斯科学院远东分院的科学家与日本东京大学的同行组成的国际研究团队近日合成了世界上首例量子金属。这种新材料具有以多晶硅为衬底的双层铊原子结构,当温度低于零下272摄氏度时,变为超导材料。据该项研究专家介绍,三十多年来,关于二维电子系统(二维金属)温度接近绝对零度时的行为(是否仍然是金属态以及是否会传导电流)的学术争论一刻也没有停歇过。通过观察这种非正常的物质状
An international research team of scientists from Far Eastern Federal University of Russia, Far Eastern Branch of the Russian Academy of Sciences and colleagues from the University of Tokyo in Japan recently synthesized the world’s first quantum metal. The new material has a double-layered thallium atomic structure with polysilicon as substrate and becomes a superconducting material at temperatures below minus 272 degrees Celsius. According to the research expert, the academic debate over the behavior of two-dimensional electronic systems (two-dimensional metals) near absolute zero for more than three decades (whether they are still metallic and will conduct electricity) has not stopped . By observing this abnormal material shape
