The evolution of the optical properties with dopant concentration has been investigated for a series of ZnO/TiOₓ multi-stacked layers having electron density exceeding the Mott critical limit of insulator-to-metal transition. These films were grown by vertically stacking multiple ZnO/TiOₓ bilayers on (0001) sapphire substrates using atomic layer deposition. The films in the sparsely doped regime s ...
