Highly-angle-resolved ultraviolet photoemission study of a black-phosphorus single crystal

Abstract
Angle-resolved photoemission spectra of a black-phosphorus single crystal have been measured with very high angular resolution using He I and Ne I resonance lines. The experimentally determined band structure has been compared with the self-consistent pseudopotential calculations. Some special points and bands with almost no energy dispersion along the interlayer direction have been successfully assigned in the experimentally derived band structure.
