III-nitride nano-LEDs for single photon lithography

We fabricated and tested III-nitride (p-GaN/MQW/n-GaN/sapphire) based nano-LEDs designed for operation in the single photon lithography technique. The band edge luminescence energy of the III-nitride nano-LEDs depends linearly on the structure size. Our studies provide clear evidence that our technological process for the vertically integrated nano-LED emitters is perfectly suited for long term operation without any indication of degradation effects. This novel technology shows strong potential for a future flexible single photon lithography [1] which is applicable for molecular photonic and electronic circuits.
