Well, almost. They tried several different ways to get the fourth terminal (connector) to the thyristor, but didn't succeed. And although they had a working DOES thyristor in the UConn lab, they didn't develop the 4-terminal variant at UConn since this was not needed in a lab setting. POET is confident that they can solve that problem eventually, but each attempt is very time-consuming and very expensive – and only afterwards you know whether you succeeded – or have to make another iteration with another approach.

Is there no software at this level (and this frontier) of engineering that can successfully simulate a new manufacturing approach in these materials with any degree of acceptable pre-fabrication accuracy? or is it one of those things where, if you have the time and resources to develop the software, you should instead develop the actual object the software would be able to tell you that you could develop?
