The base width of a npn bjt at a temperature of 300k is


The base width of a npn BJT at a temperature of 300K is 4μm. If the time it takes for an electron to diffuse a distance d is t=d2/Dn, where D is the diffusion coefficient.Calculate α and ß for this BJT. Assume typical electron mobilities and the whole lifetime in the base is 1µs.
