Cooling low-dimensional electron systems into the microkelvin regime

Cooling electrons into the microkelvin temperature range is of interest both for practical purposes and fundamental studies, but current demonstrations are limited to small, specific devices. Here, the authors achieve sub-millikelvin temperatures in a large-area, two-dimensional electron gas.
