Golf, the point is very simple, there is a material that can perform better than theoretically Si-28 wafers. After all, the advantage in thermal conductivity is at best 50%, but if another material could discharge the desired function (in essence switching) at 50% less energy per switching (and in practice, the critical factor is really the product of switching time the heat dissipation per switching), there would be no need for Si-28. Well, there is such a material, GaAs, but its cost of raw materials is about 20 times that of silicon, thus it is relegated to the most difficult part (highest switching speeds) of the microelectronics requirements. Since Si-28, has no chance of being better than GaAs, I doubt that at the huge premium it will ever find any mass market. I said that last year on this thread.
Just because Yale has received some patents it does not means these are useful, it is time that industry looks more critically at those Ivy generated patents, many are not really that useful.
