Depletion region widened pn junction

Semiconductor cross-section of a p-n junction with red p-type material on one side and blue n-type material on the other, separated by a visibly widened depletion region. The depletion region is shown as a broad pale light-colored band, clearly thicker than a normal depletion zone and associated with reverse bias. Fixed negative ion charges line the p-side edge of the depletion band and fixed positive ion charges line the n-side edge, emphasizing the expanded space-charge region.
