Impedance Spectroscopy of Nanostructure p-ZnGa2Se4/n-Si Heterojunction Diode

“…Then, the values of Z merge at higher frequencies for all the studied temperatures. The merger of both Z and Z values at higher frequency region may possibly be an indicative of the accumulation of space charge in the device [10,15]. The peak values of Z max shifts to the higher frequencies with increasing temperature i.e.…”

“…While direct current-voltage characteristics of the device give a resistive response, alternating current-voltage characteristics give both a resistive and a capacitive response [9]. The complex impedance spectroscopy is an important tool to analyze the electrical properties and to get more information about the relaxation process of the investigated device [10]. It allows the investigation of intrinsic material parameters such as the frequency dependence of real and imaginary parts of impedance as well as the internal structures of the device [11].…”

Surface morphology and corrosion inhibitors of acrylate/carbon nanotubes nanocomposites coated on mild steel

“…The CNTs has assumed as functional additives materials to polymeric materials such as acrylate incorporating with CNTs. Besides that, there are facilitate hopping process of electrons between valence and conduction bands as a donor and acceptor sites due to appearance of CNTs in acrylate [13]. Fig.…”
