Webbinjection), (8.2.12) Equation (8.2.12) illustrates that the base Gummel number is basically proportional to the base dopant density per area. The hi gher the base dopant density is, the lower the IC will be for a given VBE as given in Eq. (8.2.9). The concept of a Gummel number simplifies the IC model because it [Eq. WebbThe above equation is usually expressed not in terms of the total photon number Np but in terms of the average photon density np in the active region by dividing both sides by Vp, p sp p a g p a g p V n v g n v g dt dn ~ 1 ~ The above equation is the main result that we will use throughout this Chapter. 11.3 Carrier Density Rate Equation
