概要
- 論文の詳細を見る
The energy band structure of black phosphorus is calculated by using self-consistentpseudopotential method. The resulting band structure has the direct minimum gap atthe point Z in the Brillouin zone in agreement with the result of the tight-bindingapproach. Effective electron and hole masses and the level shift of the band edge bypressure are calculated from the bands obtained. T'he pressure dependence of theenergy gap is in good agreement with experiment, but the anisotropy of the effectivemasses contradicts that of the electrical conductivity measured for the single crystal.The nature of the optical absorption edge is discussed in terms of' the calculated bandstructure.
