Fig. 3: TERS imaging of monolayer WS2.
From: Investigating heterogeneous defects in single-crystalline WS2 via tip-enhanced Raman spectroscopy
a Peak distribution image for A1g mode derived from Fig. 2. b A1g peak skewness image. c Peak distribution image of D mode. TERS spectra were extracted from the d middle and e edge regions of the α-domain, and the f middle and g edge regions of the β-domain. Each colored (numbered) circle in the TERS images corresponds to the spectra of the same color (number). These spectra d–g were fitted using Lorentzian functions.
