I am new to this area. I would like to study these concepts from beginning onwards.
I am old, therefore I can suggest you old books: Mc Crum, Read, Williams. Anelastic and Dielectric Effects in Polymeric Solids, P. Hedvig: Dielectric Spectroscopy, A.K. Jonscher: Dielectric Relaxation in Solids, you can also use the dowloadable pdf files of Novocontrol company, which are good introductions.
First study some books and papers, study about Physical aspect of Dielectric materials and also study about giant dielectric materials. Books suggestion for you: Advances in Electroceramic Materials, Fundamentals of Ceramics (Series in Materials Science and Engineering), Materials Science and Engineering, An Introduction, High-k Gate Dielectrics.....then study about dielectric spectroscopy and interpretation of the results...
Dear Ganaga
My suggestion is if you are new in the field and have instruments of Nova control please so the following things:
1. Take sample, electrode it (if required) then do the impedance Vs frequency measurements. Choose frequency range 10Hz to 1MHz (You can choose different frequencies). Do this measurement at room temperature.
2. Change the temperature and repeat the measurement mentioned above. Take 3-4 temperatures of your choice.
Plot data at each temperature and see it carefully. Then open any book mentioned by Gyorgy or Ioannis. Try to explain your results on the basis of these book.
So my suggestion is if you read after doing experiment you will learn quickly.
good luck and well come to the field of Relaxation
Dear Gurvinderjit Singh ,
Thank you Very much for giving valuable answer.
I will definitely follow this procedure and it looks easy to do experiment.
I have sample with density of 95% .
Thank you.
@Ioannis: Dr Hedvig was my first boss and master at the Research Institute for Plastics in the early 1980's. I will always remember him with high appreciation and gratitude. I learned polymer physics pretty much from him, as it was not part of my normal chemistry curriculum. At that time we could only dream of the advanced technology nowadays available in dielectric spectroscopy ... Nevertheless it was a nice time.
In addition to what suggested for experiment point of view above, with the same data you may study dielectric response with frequency and then its modulus representation using formulas which are well mentioned in the literature and books, this will give you information about relaxation phenomenon in your system. not only this with your dielectric data you may predict the ion dynamics in your system.
Dear Dr. Gangaprasad,
