Outline:Semiconductors Open the PhET simulation using Java. About the simulation interface. How a battery acts as driving force in a circuit. Add dopants to move the electrons in the circuit. Explanation of why a pn junction acts as a diode, and allows current to flow one direction only. About valence band and conduction band. Connect the circuit in forward bias and reverse bias using a pn junction diode. Add dopants to move the electrons to higher energy levels. Show that p type dopant is an acceptor and n type dopant is a donor. Explanation of why a depletion region does not allow current to flow.
