The conditions for the appearance and the spectrum of localised electron states are reviewed for various inhomogeneous structures made of narrow-gap semiconductors with mutually inverted energy bands. The methods of supersymmetry and factorisation are used to solve Dirac-type equations with inhomogeneous external potentials in one-dimensional, two-dimensional, and three-dimensional systems.
