There is an anomalously large amount of science we don’t know about the limits of the Quantum Anomalous Hall Effect (QAHE), especially as a resistance standard.  This includes why the  quantization fails above a fairly low temperature (less than 1 K) and fairly low current (less than 1 nA).  In this “speculation” talk, I will discuss our thoughts about future experiments in the GHz and THz ranges, which we hope will allow us to decrease the amount of science we don’t understand.
