A p-type semiconductor is a type of semiconductor. Ordinary semiconductors are made of materials that do not conduct (or carry) an electric current very well but are not highly resistant to doing so. They fall half way between conductors and insulators. An electric current occurs when electrons move through a material. In order to move, there must be an electron 'hole' in the material for the electron to move into. A p-type semiconductor has more holes than electrons. This allows the current to flow along the material from hole to hole but only in one direction.
Semiconductors are most often made from silicon. Silicon is an element with four electrons in its outer shell. To make a p-type semiconductor extra materials like boron or aluminium are added to the silicon. These materials have only three electrons in their outer shell. When the extra material replaces some of the silicon it leaves a 'hole' where the fourth electron would have been if the semiconductor was pure silicon.
P-type semiconductors are made by doping the pure semiconductor material. The amount of impurity added is very small compared to the amount of semiconductor. The exact character of the semiconductor change be changed by changing the amount of 'dopant' that is added.barbour international wax jacket stylish snow boots womens what is partnership in a business jupiter merlin worldwide portfolio coventry building society online banking clear stylish glasses what are external factors in business christmas panto 2022 voxi international calls fa cup final viewing figures worldwide when's international men's day charlotte theme park worldwide christmas decor is halifax a building society international days 2022 uk stylish armchair worldwide patent the importance of communication worldwide vaccine count how to make a business successful worldwide auctioneers international currency exchange building society roll number bank of communication old mutual international how to start ice cream business south bank christmas market online communication courses stylish vanity units stylish backpack outdoor revolution drive away awning where can i buy mind your own business plant www yorkshire building society tailored-communication how to get your business on google white christmas tree international parcel tracking how long do international bank transfers take stylish brother a cardinal elimination communication stylish clothes for 70 year old woman society if meme how to start a tattoo business international drinking rules is the gas shortage worldwide
