The electronics industry might look very different today were it not for the dramatic drop in cost of high-quality single-crystalline silicon wafers over the past five decades. So what would happen if the cost of single-crystalline ...
A team of Northwestern University materials science researchers have developed a new method to view the dynamic motion of atoms in atomically thin 2-D materials. The imaging technique, which reveals the underlying cause behind ...
