Researchers at Japan's RIKEN Center for Emergent Matter Science have pioneered a method to carve three-dimensional nanoscale devices from single crystals using focused ion beams. By shaping helical structures from a magnetic crystal, they created switchable diodes that direct electricity preferentially in one direction. This geometric approach could enable more efficient electronics.

Scientists have developed a working memory chip just 10 atoms thick, integrated with conventional chips to potentially boost storage in smartphones and other electronics. The prototype, made from 2D materials, addresses limits in current chip stacking. While promising, experts note it is far from commercial readiness.

Researchers have achieved a breakthrough by pushing electrons in graphene to supersonic speeds, creating a hydraulic jump similar to a sonic boom. This experiment, conducted using a microscopic nozzle, marks the first observation of such electron behavior. The findings could help resolve debates on electrically charged shockwaves.
