Sculpting complex 3D nanostructures with a focused ion beam

Twisting a Crystal at the Nanoscale Changes How Electricity Flows

Scientists have shown that twisting a crystal at the nanoscale can turn it into a tiny, reversible diode, hinting at a new era of shape-engineered electronics. Researchers at the RIKEN Center for Emergent Matter Science, working with collaborators, have created a new technique for building three-dimensional nanoscale devices directly from single crystals. The approach uses [...]

Sculpting complex 3D nanostructures with a focused ion beam

Scientists from the RIKEN Center for Emergent Matter Science and colleagues have developed a new way to fabricate three-dimensional nanoscale devices from single-crystal materials using a focused ion beam instrument. The group used this new method to carve helical-shaped devices from a topological magnet composed of cobalt, tin, and sulfur, with a chemical formula of Co₃Sn₂S₂, and found that they behave like switchable diodes, meaning that they …
