Using qualitative considerations based on a two-center approximation for tight-binding-model matrix elements, we demonstrate that Rashba interactions in complex-oxide two-dimensional electron gases are due primarily to changes in metal-oxygen-metal bond angles at surfaces and interfaces. We verify this conclusion by comparing our picture with illustrative ab initio electronic structure calculations.
