摘要

Provided is a transition metal hydroxide film or the like with a controlled alignment. An aspect of the invention is an a-cobalt hydroxide film formed on a substrate, wherein the a-cobalt hydroxide is characterized in that the c axis of the a-cobalt hydroxide is roughly perpendicular to the substrate surface. The configuration makes it possible to obtain an a-cobalt hydroxide film with a controlled alignment and the material obtained may be expected to have various improved characteristics. Another aspect of the invention is a manufacturing method of a-cobalt hydroxide characterized in that a-cobalt hydroxide is formed while raising pH by mixing ammonia gas into a cobalt ion solution. The configuration makes it possible to obtain a-cobalt hydroxide easily.
