New property of electrons may lead to novel electronic devices
How electrons conduct electricity depends on their valley
meet demand for smaller, more powerful electronics, engineers are
struggling to find ways to store more information in a smaller area.
Today’s computers store information digitally as a series of 1’s and 0’s
using two fundamental properties of electrons: their charge (which
enables flash drives) and their spin (which enables hard disks). To
date, advances in digital storage have relied on a simple approach:
writing smaller 1’s and 0’s.
A recent breakthrough at Cornell University may enable a different approach.
