2.47. Figure P2.47 gives the electron and hole concentra- tions in a 2-um-wide region of silicon. In addition, there is a constant electric field of 25 V/cm present in the sample. What is the total current density at x = 0? What are the individual drift and diffu- sion components of the hole and electron current densities at x = 1.0 um? Assume that the elec- tron and hole mobilities are 350 and 150 cm-/V . s, respectively. E 1.01 X 1018 p(x) 1018 1016 n(x) 104 *=0 x = 2 um Figure P2.47
