a dI/dV spectra captured at Top, Hollow-1, and Hollow-2 areas of 1T-NbSe2. b, c STM images of SL 1T-NbSe2 at −0.3 and +0.6 V, respectively. d, e STM images captured with 0.2 V, 0.02 nA, and 0.2 V, 0.1 nA, respectively, showing √3 × √3 R30° superstructure (with unit vectors c1 and c2) with respect to the CDW pattern (with unit vectors b1 and b2). f Corresponding FFT of e. Tunneling parameters: a −1 V, 0.02 nA before turning off feedback loop. Scale bar for b–e: 2 nm.
