7. 利用离子液体调控和强磁场压制超导,首次获得了FeSe体系奇异金属态的系统实验证据,证实A10.5~Tc对FeSe基超导体同样成立。这一结果说明两大高温超导家族—铁基和铜基超导体具有相似的规律,表明高温超导与奇异金属态之间的相互作用具有普适性【Nature Physics 19, 365 (2023)】。
6. 发展连续组分单晶薄膜与跨尺度表征技术,制备出具有连续化学组分的高温超导组合单晶薄膜,将物性识别精度提升两个数量级至万分之一,进而首次揭示奇异金属线性电阻斜率A1与高温超导转变温度Tc之间的定量化物理规律,A10.5~Tc,说明二者存在共同驱动机制【Nature, 602, 431 (2022)】。

4. 在同一个绝缘的铜氧化物母体引入易失和非易失超导电性,提出了一种新的利用离子液体修复氧空位的调控机理。【Science Bulletin, 65, 1607 (2020)】
3.利用氢化锗烯加热去氢化成功制备多层锗烯,并首次成功测量其电学输运性质,观察到绝缘体-金属相变,实现P-型场效应晶体管,同时获得氢化锗烯中强自旋轨道耦合作用的证据。【Nano Letters, 19, 1520 (2019)】
