Well then you'll have no trouble demonstrating it and you will receive the accolades, the fame and the fortune that creating the first room-temperature superconductor will bring you.
That's not the case, though. If you say "I've got a room temperature semiconductor" (or a reactionless drive, or an antigravity machine, or whatever) and tell people how you did it, people will _absolutely_ try to reproduce that. Not just academic institutions, either; the US Navy has a bit of a history of trying to reproduce obvious nonsense, in particular.
There’s lots and lots of academic research. And a fair bit of Department of Energy money flowing into those labs. There’s lots of interest. There’s lots of papers.
And the great thing about those who “do proper science” in materials research: you can do actual science by repeating and verifying the experiments.
we already have plenty of evidence that even science people (flawed humans, like us all) cannot "do proper science" because they are swayed by irrational arguments such as distaste, shame, appeals to tradition, conformism etc. etc.
