Funding: This research was mainly supported by Quantum Energy Research Centre, Inc. and was also partially supported by Basic Science Research Program through the National Research Foundation of Korea (NRF) funded by the Ministry of Education(2019R111A1A01059675) and Young-Wan Kwon is supported by a Korea University Grant.

I don't know, either: what's the difference between receiving funding for research and taking investment money for it? Are you talking about public vs private funding?
