Semiconductor materials classification
Semiconductor materials contain not only elements, but also chemical compounds. Semiconductors can be organic and non-organic, crystalline and amorphous, solids and liquids. Despite the…
Dielectric polarization and it’s kinds
Polarization is a dielectric state when every unit of a dielectric volume has its electrical moment. There are two types of polarisation - occurring…
Shift current – conductivity of dielectrics
The polarisation processes of charge shift, until the equilibrium state of dielectrics, are followed by shift current (polarisation currents). Shift currents of elastic bounded…
Dielectric losses
Dielectric losses is the electrical power that is wasted by heating the dielectric in the electric field. Energy losses occur at the constant and…
Dielectric breakdown
A dielectric in electromagnetic fields can lose its insulator properties if the field exceeds some critical value. The phenomena of the formation of a…
