Enhanced power factor of textured Al-doped-ZnO ceramics by field-assisted deforming
Field-assisted deforming method has been used to prepare c-axis textured Al-doped-ZnO Ceramics (AZO) ceramics. In such cases, AZO ceramics with different degree of texture can be controlled efficiently. As a consequence, the electrical conductivity has been significantly enhanced for AZO ceramic with high degree of texture. The electrical conductivity for highly textured AZO is as high as 29.5 Sm-1, 6 times higher than random orientation AZO ceramics. The enhanced electrical conductivity leads to a higher power factor of 5.3x10(-4) Wm(-1)K(-2) at 750 K, a 60.6% improvement over the random orientation AZO ceramic.
