Transport properties of superconductor-based LED

What is it about?

Superconductor-based LED is a next-generation LED where superconducting Cooper pairs instead of normal electrons are involved in the radiative recombination process. In this paper, we quantitatively investigate the transport properties of superconductor-based LED in the context of superconducting three-terminal device, and discuss the radiative recombination process.

Why is it important?

Via the transport properties, this paper provides the fundamental data and concept necessary for the future design of superconductor-based LED.

Perspectives

Since the device investigated here is in strong light-confinement regime, the simultaneous measurement of light emission and of transport was not performed. The coherence of emitted light due to superconductivity is to be confirmed.
