The region of a silicon device that is at room temperature (T= 300 K) is doped with 10¹5 cm³ acceptor atoms. A stream of minority carriers is injected at x = 0 and the distribution of minority carriers in the sample is assumed to be linear, decreasing from a value of 10¹¹ cm³ at x = 0 to the equilibrium value at x = W, where W is 10 microns. (20 marks) Sketch the region. b. Determine the diffusion current density of electrons.
