A small difference between the rhombohedral phosphorus lattice (A-7 phase)
and the simple cubic phase as well as between phosphorene and the cubic
structure is used in order to construct their quasiparticle band dispersion.
We exploit the Peierls idea
of the Brillouin zone doubling/folding, which has been previously employed
in consideration of semimetals of the V period and IV-VI semiconductors.
In a common framework, individual properties of phosphorus allotropes are
