Barrier‐Assisted Plasma Doping for Spatially Selective Resistance Engineering in MoS2 Transistors

open access: yesAdvanced Materials, EarlyView.
Barrier‐assisted NH3 plasma doping enables damage‐free, spatially selective carrier modulation in monolayer MoS2 transistors. An ultrathin pV3D3/Al2O3 protective‐dielectric stack acts as a chemical filter that allows NHx radicals to reach the MoS2 surface while blocking plasma damage. This process achieves a high electron concentration of 4.3 × 1013 cm−
