Abstract

Room-temperature superconductivity has always been regarded as the ultimate goal in the fields of solid-state physics and materials science, with its realization holding revolutionary significance, capable of triggering significant changes in energy transmission and storage. However, achieving it poses various challenges. Recent research revealed that material Pb_10-xCu_x(PO₄)₆O displays room-temperature superconductivity under atmospheric pressure, sparking global interest in further exploration. Here, we utilized solid-phase synthesis to obtain a polycrystalline sample of Pb_10-xCu_x(PO₄)₆O. X-ray diffraction confirmed its structural consistency with referenced literature. Zero resistance, which is important evidence for superconductivity, was observed above 100^∘ K under ambient pressure in our experiment. Our finding indicates that Pb_10-xCu_x(PO₄)₆O is a possible candidate for searching high-temperature superconductors.

• 중국 그룹이 100 K 에서 초전도를 봤다고 주장. 아쉽게도 저항 데이터만 봐서는 초전도라고 말하기가 어려워 보인다. 전도성이 강한 불순물이 저온에서 전기 전도 측성 기여가 커지면서 나오는 결과일지도. https://arxiv.org/abs/2308.01192?fbclid=IwAR2thydJxDcnmz3LwvVVZxZ9r0JC92u7TAXlj8SjvyeeQ [bsky, 0 points, 0 comments]
