Abstract: Barium titanate nanotubes arrays were synthetized by in-suit hydrothermal method using TiO₂ nanotubes as both template and reactant in titanium substrate. Highly ordered nanotubes arrays and the spacing between nanotubes are apparent. XRD indicates that the samples have excellent crystallization and perovskite structure. Typical ferroelectric hysteresis loop of as-formed barium titanate nanotubes arrays with remanent polarization and coercive field are 6.72 and 48.7kV/cm.

Abstract: An unusual contrast in SEM secondary electron imaging for PVT grown silicon carbide with vanadium doped was observed. An explanation in point of the compensation of different type of dopant was drawn. And the relationship between the doping properties of vanadium and orientation of SiC domains was investigated.
