Example Sentences

The polycrystalline tin selenide the team makes is spiked with sodium atoms, creating what is known as a “p-type” material that conducts positive charges.

From Science Magazine

Once n-type and p-type tin selenide devices are paired, researchers should have a clear path to making a new generation of ultra-efficient thermoelectric generators.

From Science Magazine

For a p–n junction, one of the semiconductors is p-type, containing an excess of positively charged electron vacancies called holes, and the other is n-type, containing an excess of negatively charged electrons.

From Nature

This process can be realized at a p–n junction, which is the interface between two types of semiconductor known as p-type and n-type.

From Nature

Eighty years ago7, dopant atoms of boron and phosphorus were added to pure silicon to produce materials called p-type and n-type silicon, respectively; these form p–n junctions, the basis of computing.
