Quantum dots, and silicon herald new functionality
Abstract:
Researchers from UCLA's Henry Samueli School of Engineering and Applied Science describe the creation of a new material incorporating spintronics that could help usher in the next generation of smaller, more affordable and more power-efficient devices. [Xiu et al., Nature Mat. (2010) 9, 337.]
While conventional complementary metal-oxide semiconductors (CMOS), a technology used today in all types of electronics, rely on electrons' charge to power devices, the emerging field of spintronics exploits another aspect of electrons — their spin, which could be manipulated by electric and magnetic fields.
"With the use of nanoscaled magnetic materials, spintronics or electronic devices, when switched off, will not have a stand-by power dissipation problem. With this advantage, devices with much lower power consumption, known as non-volatile electronics, can become a reality," said the study's corresponding author, Wang, whose team carried out the research. "Our approach provides a possible solution to address the critical challenges facing today's microelectronics industry and sheds light on the future of spintronics."
