Can PFM phase image be useful to extract multi-state polarization level of ferroelectric thin films?

I want to polarize my ferroelectric PVDF-TrFE thin films in different directions and probe it using PFM. I know that PFM phase can read either 0o or 180o. Can it read any other orientation in...

What is use of phase, amplitude, and amplitude error images obtained in atomic force microscopy?

The use of AFM height images we normally know. But I have doubt regarding the phase image. Is this the original phase information that we are normally getting from XRD and all? What does the color...

Why don't PVDF thin films on glass or Si substrates not give proper raman peaks ?

I have tried the raman measurements of very thin PVDF films (from 70nm to 250nm) using confocal raman spectroscopy by RENISHAW. I have the following doubts, kindly give me suggestions. 1)For PVDF...

How do I correctly measure the thickness of film using AFM?

I have scanned the edge of a PVDF thin film using AFM to know the thickness. The section analysis is attached with this. Even after flattening the image, the steps are look like curved. Can...
