a Band structure of 1 L TiPd5I2 with the highest valence band (N) and band below (N-2) shown in red and blue, respectively. b Wilson loop of Wannier charge center (WCC) between band N and N + 2. c Wilson loop between band N–2 and N. d Edge spectral functions along \(\bar{X}\)-\(\bar{\varGamma }\)-\(\bar{X}\) on TiPd- and e PdI-terminations.
