Unusual photoinduced changes in the electrical conductivity of ferrocene-doped poly(methyl methacrylate) thin films prepared under different relative humidity condition

Electrical conductivity in solution cast (using chloroform as solvent) ferrocene-doped poly(methyl methacrylate) (PMMA) thin films were studied under photoexcitation by using surface-type sample cells at various temperatures. Photoinduced enhancement in c
