Hole is equivalent to:

Explanation

In semiconductor physics, a "hole" is considered the absence of an electron in a covalent bond within the crystal lattice of a semiconductor material. It's often treated as a mobile positive charge carrier. Conceptually, a hole can be seen as a positively charged entity that moves within the crystal lattice in response to an applied electric field. It behaves as if it were a positively charged particle, even though it's essentially the absence of a negatively charged electron. In terms of electrical behavior, it can be mathematically treated as a positively charged carrier moving through the material.
