美国麻省理工学院的科学家日前宣布,已开发出有史以来最小的砷化铟镓晶体管,其长度仅为22纳米。随着硅晶体管降至纳米尺度,器件产生的电流量也不断减小,从而限制了其运行速度,这将导致摩尔定律逐渐走到尽头。为了延续摩尔定律,科学家们一直在寻找硅的替代品,以能在较小尺度上产生较大电流,其中之一便是砷化铟镓。麻省理工学院微系统技术实验室的科学家研究 Massachusetts Institute of Technology scientists recently announced that it has developed the smallest ever InGaAs transistor, which is only 22 nanometers in length. As silicon transistors are reduced to nanoscale, the amount of current generated by the device is also diminishing, limiting its speed, which will eventually lead to the end of Moore’s Law. In order to continue Moore’s Law, scientists have been looking for alternatives to silicon to produce larger currents at smaller scales, one of which is indium gallium arsenide.
