The diffusion of charged species in solids is a very important part of the study of the electrical properties of materials. Electrical measurements using alternating current (ac) impedance is a powerful technique to study diffusing species in metal oxides as well as polymers. Three case studies are being presented here whereby the electrical properties of LiTaO3, Poly[2-methoxy-5-(2’-ethylhexyloxy)-(p-phenylenevinylene)] (MEH-PPV) and its composite are being studied using the same ac impedance technique. LiTaO3 is a metal oxide while MEH-PPV is a polymer. They are very different and therefore present very good examples for the versatility and power of ac impedance method. Electrical parameters such as conductivity and conduction behaviours of the conducting species can be extracted from the studies. The kinetics of the diffusing species can be elucidated by using proper analytical techniques.

In this study, the dielectric properties and alternating-current (ac) conductivity of Au/(PVA/Ni,Zn acetates)/n-Si Schottky diodes (SDs) were determined by the measurement impedance technique. Dielectric properties and electrical conductivity of Au/(PVA/Ni,Zn acetates)/n-Si SDs in the frequency range of 0.5 kHz to 10 MHz and voltage range of À2 to 5 V were investigated in detail using experimental C-V and G-V measurements. Experimental results show that the values of the dielectric constant (e 0 ), dielectric loss (e 00 ), and tan d obtained from the measured capacitance and conductance have been a strong function of frequency and applied voltage, and the values of e 0 have been unexpectedly found to be negative, especially at high voltages. Other parameters of Au/(PVA/Ni,Zn acetates)/n-Si SDs, such as ac electrical conductivity (r ac ), the real part of electric modulus (M 0 ), and the imaginary part of electric modulus (M 00 ) varied with changing frequency for various voltages. The main propose of this study is to discuss the polymeric interfacial layer at metal and semiconductor affect and probe the dielectric properties of Au/(PVA/ Ni,Zn acetates)/n-Si SDs regarding the negative capacitance as a function of frequency and voltage.
