P-type semi-conductor
A group to three atom (Boron, Indium)- acceptor atom, is used as an impurity to bond covalently in the lattice of a pure semi-conductor (Silicon). Of the four electrons of silicon, three are used to bond with three electrons of Boron, leaving one electron unbounded. There's thus a hole created, withRead more
A group to three atom (Boron, Indium)- acceptor atom, is used as an impurity to bond covalently in the lattice of a pure semi-conductor (Silicon). Of the four electrons of silicon, three are used to bond with three electrons of Boron, leaving one electron unbounded. There’s thus a hole created, with silicon, which contributes for bonding with Boron, thus holes become majority charge carriers. This results to a semi-conductor called p-type (extrinsic semi-conductor)
