hole model

hole model in Technology

A model of semiconductor behaviour in which donors contribute a positive charge equal in magnitude to the charge of an electron, and acceptors contribute space for such a charge within the crystal lattice. Honored by history well before electrons were discovered and described, much of electronics, especially at the engineering level, continues to consider current as flowing from positive to negative.
