抄録

Angle-resolved photoemission measurements with synchrotron radiation (about 20-50 eV) have been carried out on a black-phosphorus single crystal to study the interlayer interaction which characterizes the essential properties of the narrow-gap semiconductor, black P. The band dispersions along the ΓZ (interlayer) direction have been successfully obtained and compared with the self-consistent pseudopotential calculation. It is found that the overall features obtained are in good agreement with the calculation although an overestimation of the interlayer dispersion and the valence-band width by about 0.5 and 1 eV, respectively, was observed in the calculation.
