PURPOSE: A hexagonal boron nitride sheet, a manufacturing method thereof, a laminated structure including the same, and an electrical device including the same are provided to be able to manufacture hexagonal boron nitride with a high definition and a large area. CONSTITUTION: A hexagonal boron nitride sheet is a two-dimensional planar structure in which a B-N bond is a sp^2 covalent bond, and the interlayer bond is a Van der Waals bond. The hexagonal boron nitride sheet has a root mean square surface roughness of about 2.00nm or less, the length of the transverse or longitudinal direction of 1mm or more. A manufacturing method of the hexagonal boron nitride sheet comprises the following steps: a step of obtaining a metallic catalyst having a sheet form with an increased grain size by a first heat treatment within a chamber; and a step of producing hexagonal boron nitride in a sheet form by a second heat treatment while supplying a nitrogen source and a boron source in a gas phase to a chamber.

PURPOSE: A ZnSnO3/ZnO(zinc stannate/zinc oxide) nanowire in a core-shell structure is provided to have excellent piezoelectric characteristic by containing ZnSnO3 in a perovskite crystalline structure, and to apply a nano power-generating device to an environment-friendly field or within the human body. CONSTITUTION: A ZnSnO3/ZnO nanowire(500) includes a core-shell structure formed with a core(510) and a shell(520). The core contains ZnSnO3 and the shell contains ZnO. The ZnSnO3 has a perovskite crystalline structure, and the ZnO has a hexagonal crystalline structure. The ZnSnO3/ZnO nanowire is formed by a thermal chemical vapor deposition(thermal CVD) method. A producing method of the ZnSnO3/ZnO nanowire comprises the following steps: mixing ZnO powder, SnO powder, and carbon powder in a determined ratio; separately inserting the mixed powder and a substrate into a furnace; and heating the mixed powder for growing the ZnSnO3/ZnO nanowire on the substrate.
