has any one measured dielectric constant of halide perovskite thin film in a simple capacitor configuration ? Or are there recent published works on the same.
A few days ago this came out for lead bromides single crystals
Article Liquid-like dielectric response is an origin of long polaron...
Can anybody suggest a suitable technique to obtain a free-standing ITO which can be later stacked on to another thin film. Basically I need to deposit ITO without damaging the existing layer.
