Built-in voltage

Built-in voltage

Hello all I have work on the following question and just wondering if you all could check to see if i did it correctly.
The built-in voltage of a GaAs pn junction diode is 1.25 V when the diode's temperature is T = 320 K. The cathode region of the diode is doped with phosphorus at a concentration of 1017 cm-3. Determine the required doping concentration in the anode region.
I will attach my work.
Thanks a lot!
