We present a green emitting single quantum dot light emitter integrated into a resonant-cavity diode design. Most important, electroluminescence stemming from one individual quantum dot is obtained at room temperature with a surprisingly low operation voltage of 2.6 V. This demonstrates that our single quantum dot device is ideally suited for electrically driven nonclassical light generation under ambient conditions.
