A spin–orbit coupling-induced two-dimensional electron gas in BiAlO3/SrTiO3 heterostructures

Both LaAlO₃ and BiAlO₃ are isostructural, isoelectronic and band insulators. Hence, first principles study using supercells are performed to determine the emergence of two-dimensional electron gas at the interface of BiAlO₃/SrTiO₃ heterostructures.
