Abstract
Provided is a method of forming a metal oxide layer may include forming a parent metal oxide layer on the substrate structure; changing the parent metal oxide layer into a cation-exchanged metal oxide layer through a cation exchange reaction between cations in the parent metal oxide layer and cations in the reaction solution by contacting the parent metal oxide layer with a reaction solution containing these latter cations; and performing a heat treatment process on the cation-exchanged metal oxide layer.
Claims19
A method of forming a metal oxide layer comprising:
- forming a parent metal oxide layer on a substrate structure;
- changing the parent metal oxide layer into a cation-exchanged metal oxide layer through a cation exchange reaction between cations in the parent metal oxide layer and cations in a reaction solution by contacting the parent metal oxide layer with the reaction solution;
- and
- performing a heat treatment process on the cation-exchanged metal oxide layer,
- wherein the parent metal oxide layer includes a first binary metal oxide, and the cation-exchanged metal oxide layer includes a second binary metal oxide different from the first binary metal oxide.
