a–c Schematics of atomic structure and corresponding Brillouin zone (BZ) of MoS2-bP superlattices, with twisted angle θ. The armchair (AC) directions of MoS2 and bP are labeled as dashed lines in panel a. d Schematic of micro-ARPES on MoS2-bP superlattices. e Scanning photoemission microscopy image (SPEM) of MoS2-bP superlattice (θ = 8.5°). The photoemission signals are integrated from the energy range of binding energy 2.1–2.3 eV and momentum range of k// = ±0.4 Å−1. Monolayer MoS2 and MoS2-bP regions are labeled in black and red dashed curves, and the measured points of micro-ARPES are labeled as circular shapes in the regions. The scale bar is 5 μm. f Determination of twisted angle θ. The angle-resolved polarized Raman spectra (ARPRS) of Ag2 vibration mode in bP with fitted curve (top) and the micro-ARPES of monolayer MoS2 at constant energy cuts of kinetic energy at valence band maximum E = EVBM (middle) and E = EVBM−0.8 eV (bottom).
