Electrically tunable TiN/SiO2/TiN epsilon-near-zero photonic structures with various parameters were fabricated using the reactive DC magnetron sputtering approach. Effective medium approximation was used to predict the optical permittivity of a multilayered TiN/SiO2 metamaterial and guide the design/fabrica...
The relative quantity of epsilon-Fe2O3 phase, the proximity or pinning effect derived from SiO2 phase as well as the phase transformation from epsilon-Fe2O3 to epsilon-Fe2O3 during etching treatment were three main factors to its controllable magnetic properties. This work will shed new light...
epsilon-Fe2O3Paramagnetic-class propertiesLarge lattice strainIn this work, the milling-etching route is designed to synthesize nanoflakes with high-content epsilon-Fe2O3 phase, which is environmental friendly and more desirable for energy-efficient mass production of epsilon-Fe2O3 phase than ...
Magnetic properties of Fe2O3/SiO2 samples were studied after being produced by sol-gel synthesis and formation of epsilon-Fe2O3 polymorph. Samples were thermally treated, using different annealing temperatures and annealing times. The size and morphological characteristics of the iron oxide ...
