Suppose the electron concentration in a piece of silicon is
Suppose the electron concentration in a piece of silicon is equal to N at x=0 and falls linearly to zero at x=L. Find the expression for the diffusion current density. Calculate the current density for N=10^16 cm-3 and L=1 µm.

At high temperature, ammonia reduces copper(II) oxide to the free metal: 2NH3(g) + 6CuO(s) => N2(g) + 3Cu2O(s) + 3H2O(g) Step 2: 2NH3(g) + 3Cu2O(s) => N2(g) + 6Cu(s) + 3H2O(g)
