If you want to read the details on how it works, I suggest this paper [1] "Large-gap quantum spin Hall insulators in tin films". The real hope is that this will be a replacement for the conductors in traditional silicon. You still have the heat bottleneck when you hit a traditional conductor. The dissipation free property breaks down at about 100C for this material, so you are going to have an issue with what ever is interacting with that 200A.
