For one of these devices, the transport factor over one minus the transport factor is equal to the gain.
One model of these devices is known as the most exquisite model. An older method for making these is the double diffused epitaxial process. For one of these devices, the transport factor over one minus the transport factor is equal to the gain. Their modes of operation are cutoff, forward active, reverse active, and saturation. They are the subject of the Gummel-Poon and the Ebbers-Moll models. The increase of a particular voltage in one causes an increase in current known as the Early effect. They can be of either pnp or npn form, and they consist of a collector, base, and emitter. For 10 points, name this type of transistor that contrast with field effect transistors.
