Room‐Temperature Tuning of Electrical Conductivity in Single MoS2 Flakes via Nanoscale Amorphization by Focused Ion Beam

open access: yesAdvanced Materials Technologies, Volume 10, Issue 20, October 20, 2025.
Focused ion beam (FIB) patterning enables on‐chip amorphization of high‐aspect ratio MoS2 monolayers into complex geometries with tunable electrical properties. By controlling the ion dose, conductive pathways as narrow as 700 nm are formed, allowing precise modulation of local conductivity.
