It was experimentally demonstrated that short-period metamorphicInAs1-xSbx/InAs1-ySby superlattices with ultra low bandgap have properties of aDirac material. Cyclotron resonance and interband magneto-absorption peaks insuperlattices with ultra-low bandgaps demonstrate a square root dependence onthe magnetic field for a range up to 16 T (energy range up to 300meV). Thisdirectly indicates the linearity of the electron dispersion. The Fermi velocitycan be controlled by varying the overlap between electron and hole states inthe superlattice. The dependence of the cyclotron resonance energy on themagnetic field parallel to the superlattice plane demonstrates that theelectron dispersion in the growth direction can be characterized by aneffective mass of 0.028m0 in a superlattice with a period of 6 nm and 0.045m0in a superlattice with a period of 7.5 nm. Extreme design flexibility makes theshort-period metamorphic InAs1-xSbx/InAs1-ySby superlattice a new prospectiveplatform for studying the effects of charge carrier chirality and topologicallynontrivial states in structures with the inverted bandgaps.
