LK-99 (from the Lee-Kim 1999 research), [2] also called PCPOSOS, [3] is a gray–black, polycrystalline compound, identified as a copper-doped lead‒oxyapatite. A team from Korea University led by Lee Sukbae ( 이석배 ) and Kim Ji-Hoon ( 김지훈 ) began studying this material as a potential superconductor starting in 1999.

2023年7月26日 · 超导量子阱 （Superconducting Quantum Well，简称SQW）是一种人工制备的薄膜纳米结构，它利用量子约束效应产生量子化的能级，从而提高超导转变温度。 然后通过热容实验，研究人员验证了LK-99具备室温常压超导能力。 具体来看，他们在389K（约125℃）下进行试验，出现了电压等于0的情况，由此认为在这一条件下电阻等于0. 作者还测试了样品的零电阻效应、临界电流和磁场的变化关系等，来论证LK-99具有超导性。 此外，他们还展示了LK-99样品 …
