Abstract
It is theoretically shown that spin-polarized vortex states with linear electronic spectrum can exist in planar homogeneous structures of two-band semiconductors at any sign of the gap parameter. These states are localized at the surface of a cylinder with a microscopic radius, have the total angular momentum of 1/2 and are stabilized when an electric voltage is applied to both sides of the planar sample.
