Experimental Formation and Mechanism Study for Super-High Dielectric Constant AlO/TiO Nanolaminates.

Super-high dielectric constant () AlO/TiO nanolaminates (ATO NLs) are deposited by an atomic layer deposition technique for application in next-generation electronics. Individual multilayers with uniform thicknesses are formed for the ATO NLs. With an increase in AlO content in each ATO sublayer, the shape of the Raman spectrum has a tendency to approach that of a single AlO layer.

Microwave Effects on Co-Pi Cocatalysts Deposited on α-FeO for Application to Photocatalytic Oxygen Evolution.

We analyze the effects of microwave applied in the process of photoelectrochemical deposition of cobalt-based cocatalysts, Co-Pi, onto well-orientated flat α-FeO thin films, which were fabricated by pulsed laser deposition. As compared with conventional heating, microwave significantly affects the morphology, chemical composition, and photocatalytic activity of Co-Pi/α-FeO composite. A significant enhancement in photocurrent related to photocatalytic water oxidation is achieved by the Co-Pi catalyst prepared under microwave irradiation.
