(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

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
Here an n-type semiconductor, such as cadmium sulphide, forms a depletion region when in contact with the p-type absorber.
From Nature • Aug. 15, 2012
In some transistors, source and drain are p-type, and channel n-type.
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.
