These "research" transistors have never had any bearing on the reality of economically manufacturing products. Here's a paper way back 50 years ago they were already making tiny transistors with electron beam processes https://ieeexplore.ieee.org/document/5391506 - it would be about another 15 years before commercial chips were made with this transistor dimension, and that's 15 years at the height of Moore's law.
Not to say they don't inform what might be possible and advance knowledge of the physics, but it's not much of a predictor about what might become economically viable to make.
