accumulation layer

https://doi.org/10.1351/goldbook.13989
Subsurface space where the majority carriers accumulate near the surface of a semiconductor because of band bending caused by the surface potential.
Note: The surface charge is of opposite sign to that of the majority charge carriers in the semiconductor. This leads to accumulation of the majority charge carriers in a subsurface layer.
See: depletion layer, inversion layer
