1. The energy given up by an electron in penetrating the cell barrier.
2. A measure of the electrostatic potential of the barrier.

A landform created by long linear wave deposits that form parallel to shorelines.

A coral reef separated from the shoreline by a lagoon.

A very thin region of static electric charge along the interface of the positive and negative layers in a photovoltaic cell.

The barrier inhibits the movement of electrons from one layer to the other, so that higher-energy electrons from one side diffuse preferentially through it in one direction, creating a current and thus a voltage across the cell; also called depletion zone or space charge.

A cell barrier, or junction between a layer, established as the interface between a semiconductor; such as, silicon, and a sheet of metal characterized by hot carriers.

Named for the German physicist Walter Hans Schottky (1886-1976).
