(a) Calculated permittivity functions for the layers composing SHM EB4910 using our new microscopic theory. (b) Permittivity functions for the individual quantum well and barrier layers composing SHM EB4910 extracted via ellipsometry. The presented functions were extracted by fitting the ellipsometry data assuming a Lorentz function for the out-of-plane permittivity of the quantum well layer and Drude functions for the in-plane permittivities of the quantum well layer.
