XANES of Co metal-organic thin films deposited by ALD

Metal-organic thin films deposited by ALD show various new structures not reachable by traditional synthesis methods. New metal-organic films with Co show interesting phenomenon where films deposited at different conditions or using different reagents result in different Co oxidation states, including Co(0). Here we use high-resolution XANES to study a series of samples with different synthesis backgrounds to verify the Co oxidation state and local environment.
