Example Sentences

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.

The results, notes Prof. Rabani, indicate that the nanocrystals have been doped with both n-type dopants, indicating the presence of excess electrons in the nanocrystals, and p-type, which contribute positively charged holes to the semiconductors.
