Abstract A single-electron emitter, based on a single quantized energy level, can potentially achieve ultimate temporal and spatial coherence with a large emission current, which is desirable for atomic-resolution electron probes. This is first developed by constructing a nano-object on a metal tip to form a quantized double barrier structure.
