A schottky diode and a pn junction diode have cross sectional areas a=10^-4. The reverse saturation current density of the pn junction diode is 3x10^-8 A/cm^2. The reverse saturation current density of the pn junction diode is 3x10^-12A/cm^2. Determine the forward bias voltage in each diode required to yeild diode currents o
Consider an ideal pn junction diode at T=300K operating in the forwared bias region. Calculate the change in diode voltage that will cause a factor of 10 increase in current.
When a potential difference of 178 V is applied to the plates of a parallel-plate capacitor, the plates carry a surface charge density of 47nC/cm^2. What is the distance between the plates? Answer in units of micrometers.
A capacitor with air between its plates is charged to 70 V and then disconnected from the battery. When a piece of glass is placed between the plates, the voltage across the capacitor drops to 43 V. What is the dielectric constant of this glass? (Assume the glass completely fills the space between the plates)
Given two plane-parallel electrodes, space d, at voltages 0 and V_0, find the current density if an unlimited supply of electrons at rest is supplied to the lower potential electrode. Neglect collisions.
