An {{w|electron hole}} is a quasiparticle denoting a ''lack'' of an electron. These are fundamental in the theory and design of semiconductors and discussed in many educational tracks regarding electronics engineering. Referring to a beam by what it seems to be doing in simplistic terms, is not typical terminology,{{Citation needed}} otherwise we might refer to "shadow beams" instead of "destructively interfering photon beams" and a "nonmagnetic field" instead of a "magnetically shielded" space. It should be noted however, that the equivalent of a hole in the QED vacuum is a real particle, known as the positron. See the {{w|Dirac sea}}. | An {{w|electron hole}} is a quasiparticle denoting a ''lack'' of an electron.

<blockquote>[A]n electron hole (often simply called a hole) is a quasiparticle denoting the lack of an electron at a position where one could exist in an atom or atomic lattice. Since in a normal atom or crystal lattice the negative charge of the electrons is balanced by the positive charge of the atomic nuclei, the absence of an electron leaves a net positive charge at the hole's location. | <blockquote>[A]n electron hole (often simply called a hole) is a quasiparticle denoting the lack of an electron at a position where one could exist in an atom or atomic lattice.
