  • Abstract:

    Nanolaminates composed of alternating layers of ZnO and Al2O3 are grown by conformal atomic-layer deposition. Their structural and nonlinear optical properties are correlated. Optimized nano­laminates exhibit an effective bulk second-order nonlinear optical susceptibility that is independent of the substrate and that is five times larger than that of potassium dihydrogen phosphate.
