The initial step during illumination in the j vs t measurements illustrates the charging effect at the moment of illumination and the corresponding decay in the current density is due to recombination of free holes accumulated at the surface with free electrons in case of n-type semiconductors. ...
Current density is the amount ofelectric currentthat flows through a unit value of the cross-sectional area.It is a vector quantity comprising both a direction and scalar magnitude. Current Density is measured in terms ofAmpereper square meter (A/m2). In the case of a steady current, the s...
A high current density over 1000 A/cmoperation in small chip size m-plane GaN-LED has been successfully demonstrated. The LED with chip size 450 × 450 μmhas emitted 1353 mW in light output power and 39.2% in external quantum efficiency (EQE) at 1000 A/cm(1134 mA). The m-plane GaN...
The conventional PWM hard switching converters are still the best choice for improving the power density, efficiency, reliability, and cost when the switching frequency of the converter is in the range of 50–200 kHz for regular commercial applications. However, there are specific applications where...

In 1963 Ridley postulated that under certain bias conditions circuit elements exhibiting a current- or voltage-controlled negative differential resistance will separate into coexisting domains with different current densities or electric fields, respecti
3-D integration using through-silicon-vias (TSVs) is emerging as one of the key technology options for continued miniaturization. However, because of increased device and current density, the reliability of the 3-D power grid and its integrity must be studied and analyzed. Due to the geometry...
To compare the current density vs. electric field characteristics of Ta2O5 films with those of SiO2, an effective field strength was calculated from the measured parameters ∈exp and Vexp [37] (exp denotes experimentally measured parameters): Eeff = CexpVexp/∈0∈s A = ∈expVexp/∈sdtot, ...
