Base collector junction

Simplified 2D semiconductor junction diagram representing the base-collector junction of a bipolar junction transistor, shown as two adjoining semiconductor regions meeting at a clear interface. The base region is narrow, while the collector region is larger. Use contrasting colors or shading for the adjacent regions, with a thin boundary line and optionally a subtle depletion band at the interface. The view may be presented as a close-up or partial transistor cross-section, with minimal technical styling and optional terminal labels indicating the base side and collector side.
