In forward biased configuration of a diode, the current increases exponentially with the voltage. A transistor is produced by an n-p-n junction. A transistor is an electric valve that controls the current in a circuit. A transistor is a critical component in audio amplifiers, computers, and many other devices.

The total charge within the gaussian rectangle is the product of the doping charge density (\rho), which is negative, and the volume of the rectangle within the depletion zone (Ax).
