摘要：
It is shown that the spin-orbit interaction (SOI) produced by the Coulomb fields of charged impurities provides an efficient mechanism for bound states formation. The mechanism is realized in 2D materials with a sufficiently strong Rashba SOI provided that the impurity locally breaks the structure inversion symmetry in the direction normal to the layer.
