Cloze (1): JXUwMDEyJXUwMDNmJXUwMDFiJXUwMDBkJXUwMDE3JXUwMDFkJXUwMDA2JXUwMDAx refers the region where the two types of semi-conductors meet. The junctions are made by combining an Cloze (2): JXUwMDM2JXUwMDQzJXUwMDU5JXUwMDBkJXUwMDA5JXUwMDE1 and p-type semi-conductor. The Cloze (3): JXUwMDM2JXUwMDQzJXUwMDVmJXUwMDE3JXUwMDAyJXUwMDBlJXUwMDA2JXUwMDAx is the cathode and the Cloze (4): JXUwMDI4JXUwMDVkJXUwMDVmJXUwMDE3JXUwMDAyJXUwMDBlJXUwMDA2JXUwMDAx is the anode. 

Forward bias occurs when the Cloze (5): JXUwMDI4JXUwMDVkJXUwMDU5JXUwMDBkJXUwMDA5JXUwMDE1 block is connected to the positive terminal and the Cloze (6): JXUwMDM2JXUwMDQzJXUwMDU5JXUwMDBkJXUwMDA5JXUwMDE1 block is connected to the negative terminal of a battery. The depletion layer of the junction reduces to be very thin to allow the flow of electric current.

In reverse bias the negative terminal of the battery is connected to the Cloze (7): JXUwMDI4JXUwMDVkJXUwMDU5JXUwMDBkJXUwMDA5JXUwMDE1 region while the Cloze (8): JXUwMDM2JXUwMDQzJXUwMDU5JXUwMDBkJXUwMDA5JXUwMDE1 is connected to positive terminal. The depletion layer Cloze (9): JXUwMDJmJXUwMDFlJXUwMDBkJXUwMDAxJXUwMDBiJXUwMDFk and resists the flow of electrons to minimal or zero .(no current flowing through)
