Hopes Dashed as LK-99 Confirmed Not to Be a Room-Temperature Superconductor
- seewhydee 3y ago> According to some of the new data, the resistivity of LK-99 increases as you lower the temperature, like some sort of anti-superconductor. The writer based this on a sarcastic tweet, taking it at face value. It seems to imply that resistance increasing with temperature is somehow startling; actually, it's how semiconductors behave (as the original tweeter knows very well).
