Let me add one more question to this.. What should be the sheet resistance for Cu2O and CuO thin films?
The copper oxides are generally semiconductors, the band gaps for Cu2O and CuO are reported to be in a range of about 2-3 eV depending on the paper that you are looking at. So the film resistivity is substantially larger compared to a metallic thin film. Practically speaking, we did some conductivity measurements in the past, and instead of some ohm (of course depending on the cross section of the film, i.e. thickness, length and width), you will probably achieve a resistance of some kilo-ohms instead for a cupric or cuprous oxide.
Hi,
It seems like this is a very late comment. However, I am working on this area, the electrical properties of copper oxide thin film, and I found that there was an inconsistence in the resistivity of Cu2O and CuO (sheet resistance also). In some articles, they reported that the resistivities of Cu2O and CuO are 10^3 - 10^8 ohm.cm and 0.01 - 1 ohm.cm in respectively [1]. In other hand, some other articles which include Mr Yurity's recommended paper, the resistivities of Cu2O and CuO are around 250 - 550 ohm.cm and 31 - 192 ohm.cm [2]. In my case, I met the result as same as the former report, but I still feel so confused. Would you please share your experience on this case?
I think should be around the range of 10^2 ~ 10^3 ohms.cm depending on which technique to synthesis, normally using thermal oxidation is the best property, like this paper below. When the resistivity changes, you should pay attention to the phase change, from Cu to oxides.
