P-type semiconductors use dopants that act as electron acceptors. Boron fits into the crystal lattice just like silicon atoms, but since boron has only three electrons to use, a kind of hole is ...

This movement of electrons, and separation from their opposite-charged "holes," creates ... transfer across a semiconductor ...

A solar cell is made of two types of semiconductors, called p-type and n-type silicon ... is required to form the bonds with the surrounding silicon atoms, an electron vacancy or “hole” is created.

Semiconductor quantum dots (QDs), consisting ... two recent papers show that an even better bet could be the absence of one electron (known as hole) or more precisely its spin 1,2.

For the first time, the formation of tiny, difficult-to-detect particles - known as dark excitons - can be tracked precisely ...
