Electric field → charge densityThe electric field in a silicon diode is described by, [V/m]. Here $x$ and $y$ are measured in meters. What is the charge density in this region? The relative dielectric constant of silicon is $\epsilon_r=12$. The permeability constant is $\epsilon_0=8.85\times 10^{-12}$ F/m. $\rho =$ [C/m³] |
