Resonance‐Enhanced Four‐Wave Mixing Imaging for Mapping Defect Regions in Vanadium‐Doped WS2 Monolayers [PDF]

Small Methods, Volume 10, Issue 19, 7 October 2026.
Resonant four‐wave mixing (FWM) microscopy reveals a spatial modulation of the third‐order nonlinear optical response in vanadium‐doped WS2 monolayers. This robust nonlinear contrast technique tracks the preferential accumulation of vanadium dopants along the structural bisection lines of the synthesized flakes.
