I would like to know if there are any methods to make thin film of transition metal nitrides transparent. I found just one paper where titanium nitride deposited by CVD was transparent. There are some papers where TiN and ZrN were applied as counterelectrode, but my goal is to replace TCF (for example ITO) with transition metal nitrides. They are conductive so this criteria should be fulfilled, however there is still criteria of transparency (transmittance should be around 0,84). I would like to deposit my thin films with magnetron sputtering. Do You have any recommendations? Thank You for any meritorious answer in advance.
A thin film should be optically transparent if the thickness of the film is lower than the optical skin depth.
Dear Michal,
by my esperience TiN and AlN coatings with thickness lower than 100nm about are transparent and TiN is an excellent conductor. The success of your coating depend on the roughness of your surface and thickness homogeneity you are a le to achieve. Be careful that coating thickness homogeneity is fundamental to ensure transparen and the risk to observe interference fringes at the corners and edges of your substrates is high!
