(of a semiconductor) having more conduction electrons than mobile holes
associated with or resulting from the movement of electrons in a semiconductor
n-type conductivity
Made of material, usually a semiconductor such as silicon, that has been doped with impurities so that it has an excess of conductive electrons.
Compare P-type

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.

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.

A p-type semiconductor is a material rich in positive charge carriers or holes, whereas negative charges make up the opposing n-type semiconductor.
From Scientific American ● Jan. 28, 2015
As transistors get smaller, however, laying down n-type and p-type materials in proximity gets harder, thanks once again to fluctuations in the concentrations of dopants.
From Economist ● Aug. 17, 2011
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.

Like opioid receptors, N-type calcium channels occur throughout the nervous system.
