3D nanocoils turn geometry into switchable diodes
TL;DR Summary
Researchers use a focused ion beam to sculpt 3D helices from a single crystal (Co3Sn2S2), creating switchable diode-like electrical transport whose direction can be reversed by changing magnetization or the helix handedness, demonstrating geometry as a design tool for future low-power, 3D nanoscale electronics.
