Spintronics, which use the spin of electrons rather than their direct motion to carry information, has emerged as one of the leading alternatives to traditional electronics, promising faster information processing and lower energy consumption. Efficient spin injection into semiconductor is a crucial first step to realize useful spintronic devices, which remains an elusive challenge up to now. Recently, a joint group from Nanyang Technological University, the National University of Singapore, and the Agency for Science, Technology and Research (A*STAR) has achieved a breakthrough in the speed and efficiency of spin injection into semiconductor.
