Toward
Achieving 1 Million Times Increase in Computing Efficiency

Modern-day
computers are based on logic circuits using semiconductor transistors. To
increase computing power, smaller transistors are required. Moore’s Law states
that the number of transistors that can fit on an integrated circuit should
double every two years due to scaling. But as transistors reach atomic
dimensions, achieving this feat is becoming increasingly difficult.
.... A paper
describing the findings, “Emitter-Coupled Spin-Transistor Logic,” was presented
July 5 at the International Symposium on Nanoscale Architectures held in the
Netherlands. Additional Northwestern authors include graduate student Joseph
Friedman, the paper’s lead author; Gokhan Memik, associate professor of
electrical engineering and computer science; and Alan Sahakian, professor of
electrical engineering and computer science.
