Using angle-resolved photoemission spectroscopy (ARPES) combined with a thin-film stretching holder, the temperature-dependent band measurements of bulk black phosphorus were initially conducted, before performing band measurements under tensile strain at 200 ℃. The results show that as the heating temperature increases from 30 ℃ to 200 ℃, the valence band maximum (VBM) gradually shifts towards deeper levels. This change is attributed to the weakening of interlayer interactions due to thermal expansion of the lattice. The strain-ARPES measurements at 200 ℃ indicate that as the tensile strain along the zigzag direction increases, the VBM exhibits a linear shift towards shallower levels, with a shift rate of 17.8 MeV/% strain. This is because at high temperatures, the tensile strain induces a greater lattice contraction in the out-of-plane direction, resulting in a more significant enhancement of interlayer interactions, which subsequently leads to a more pronounced VBM shift.
