HOUSTON - (Feb. 25, 2021) - A new theory by Rice University scientists could boost the growing field of spintronics, devices that depend on the state of an electron as much as the brute electrical force required to push it.
Materials theorist Boris Yakobson and graduate student Sunny Gupta at Rice s Brown School of Engineering describe the mechanism behind Rashba splitting, an effect seen in crystal compounds that can influence their electrons up or down spin states, analogous to on or off in common transistors.

In 1980, home computers had been available for five years, Sir Tim Berners-Lee established the precursor to the World Wide Web, and hard disk drives held a mere five megabytes each. That year, the Department of Energy’s (DOE) Office of Energy Research – now the Office of Science – had a small but dynamic program in applied mathematics, advanced computing, and networking for scientific research. Forty years later, the program, now called Advanced Scientific Computing Research (ASCR), still supports advances in scientific progres
