It's important. Pls answer. Thank you.

(cm) N P n=10 p=109 4.32P) The figure shows carrier densities of a Si PN junction diode. Before solution choose suitable positive integer values of a and b (a>b) and show this numbers clearly in a box. a) Write the bias type and explain your reason. Calculate the bias voltage. (n=10') b) What are the equilibrium values of minority carriers? c) Calculate the hole concentration on the N side at x=0. d) Diffusion constants of electron and holes has Dn=cDp relation.(Choose the c value between 0b) and show this numbers clearly in a box. a) Write the bias type and explain your reason.
