ZnO multipods, submicron wires, and spherical structures and their unique field emission behavior

Article Abstract:

A study demonstrates a simple method of vapor deposition for the shape selective synthesis of ZnO structures, namely, multipods, submicron wires, and spheres. Results suggest that the growth of a multipod structure is governed by the screw dislocation propagation while the vapor-liquid-solid (VLS) mechanism is responsible for the formation of submicron wires and spheres.

Shape selective synthesis of unusual nanobipyramids, cubes, and nanowires of RuO2: SnO2

Article Abstract:

A novel nanobipyramidal structure along with nanowires and cubes of tin oxide are synthesized by employing RuO2 as a promoter/nucleating gent. The nanobipyramids are collected in the downstream where the temperature is between 2090 and 500 degree Celsius, whereas nanowires and cubes are formed on the substrate containing the reaction mixture.

Effect of RuO2 in the shape selectivity of submicron-sized SnO2 structures

Article Abstract:

Several dissimilar types of tin oxide microstructures including bipyramids, cubes and wires synthesized effectively by means of a simple approach were investigated. The result suggested that the bipyramids were formed because of the vapor-solid process (VS) while wires and cubes were formed by the vapor-liquid-solid progression.
