What is maximal working temperature range?

  They have tested their devices at 300 Celsius degrees, but significantly higher temperatures should be possible, e.g. 500 or 600 Celsius degrees. It is likely that the upper working temperature would not be limited by the semiconductor channel, but by the accelerated degradation of the metallic conductors, which would limit the lifetime of the devices. Conductors with better chemical and electromigration resistance would have higher electric resistivity, lowering the speed of the devices.

  Good question. Couldn't see any immediate answer. They characterize the device at 300C, but the supplemental material[1] shows experimental data on the phosphorus layer up to 600C.
