Breakthrough in Semiconductor Spin Wave Research

Abstract:
UCLA Engineering adjunct professor Mary Mehrnoosh Eshaghian-Wilner, researcher Alexander Khitun and professor Kang Wang have created three novel nanoscale computational architectures using a technology they pioneered called "spin-wave buses" as the mechanism for interconnection. The three nanoscale architectures are not only power efficient, but also possess a high degree of interconnectivity.

In contrast to traditional information processing technology devices that simply move electric charges around while ignoring the extra spin that tags along for the ride, spin-wave buses put the extra motion to work transferring data or power between computer components. Information is encoded directly into the phase of the spin waves. Unlike a point-to-point connection, a "bus" can logically connect several peripherals. The result is a reduction in power consumption, less heat and, ultimately, the ability to make components much smaller as no physical wires are actually used to send the data.
