- noun a semiconductor material such as silicon which has a substance added to increase the number of negatively charged electrons and thus increase electrical conduction
- A semiconductor material which has the addition of pentavalent dopants, such as arsenic or antimony, which contribute free electrons which increase the conductivity of the intrinsic semiconductor. In this manner, the concentration of conduction band electrons is much higher, making electrons the majority carrier. This contrasts with a p-type semiconductor, in which holes are the majority carrier. Also called n-type material, or n-type (1).
- synonymn-type material
- noun a semiconductor doped with a substance which provides extra electrons in the material, giving it an overall negative charge compared to the intrinsic semiconductor
