The barrier potential of a p-n junction depends on : (i) type of semiconductor material (ii) amount of doping (iii) temperature. Which is one of the following is correct?

A p-n junction diode can not be used

The barrier potential in a p-n junction diode is 0.3 volts . The current required is 6 mA. If a resistance of 200 Omega is connected in series with the junction diode then the e.m.f. of the cell required for use in the circuit is
