Temperature dependent current voltage (I-V) characteristics, capacitance-voltage (C-V), conductance-voltage (G-V), frequency dependent capacitance for understanding the dielectric properties are the basic measurements you can go for. Also, few advanced measurements including current transient, voltage sweep in cycles of +ve and -ve polarities would provide the possibility towards new applications.

Dear colleagu Ajit Kumar Mahapatro,

these are very good recommend , I will fellow them.

but if you please, how can be measured or calculate the dielectric constant

thank you very much

but if you please, how can be measured or calculate the dielectric constant

Dielectric constant can be measured from the capacitance as C= (Dielectric constant) X Area / distance.

Dear Ajit Kumar Mahapatro

but , From where the capacitance can be get

You can sandwich the thin film of nanoparticles between two electrodes and go for the C-V measurements of various flavours with frequency and voltage dependences, using LCR/capacitance meter. Also, you can use an external voltage source if you need higher voltages or if you use a capacitance meter. You can search the literatures/ books to perform the capacitance-voltage experiments in the lab.
