Researchers build room-temperature spintronic computers

摘要

Researchers at the Uni- versity of Utah have built spintronic transistors to align the magnetic spins of electrons for a record period of time in silicon chips at room temperature (Reference 1). "Electronic devices mostly use the charge of the electrons, a negative charge that is moving," says Ashutosh Tiwari, an associate professor of materials science and engineering at the university. "Spintronic devices will use both the charge and the spin of the electrons. With spintronics, we want smaller, faster, and more power-efficient computers and other devices."
