稀土磁性材料;稀土过渡金属氧化物薄膜与异质结构的磁性及磁输运行为;金属性导电氧化物界面及自旋-轨道耦合效应。
1)制备了KTaO3金属性导电界面新体系,并利用光调控、晶向调节等手段实现了KTaO3界面Rashba效应的极大增强(Adv. Mater. 2023, Adv. Mater. 2024);
2) 在国际上首次提出并证明了电荷转移导致的氧化物界面二维电子液体的调制掺杂原理 (Nat. Mater. 2015)使氧化物界面二维电子液体的电子迁移率提升了大约 100 倍,成功观测到氧化物界面二维电子液体的多量子阱量子霍尔效应(Phys. Rev. Lett. 2016),同时发现电声耦合降低是调制掺杂氧化物界面迁移率大幅提升的主要原因(ACS Nano 2022);
3)结合调制掺杂以及磁近邻效应制备了稀磁氧化物界面(Adv. Mater. 2019) , 首次获得了高迁移率磁性二维电子液体并发现了可能的超导与铁磁共存基态 ;
4) 首次发现了非对称性氧化物界面(尖晶石与钙钛矿 gamma-Al2O3/SrTiO3 异质界面)二维电子液体 (Nat. Commun. 2013)。这是第一个非全钙钛矿体系外延界面处的高迁移率二维电子液体,打破了过去十年来钙钛矿与钙钛矿同质界面垄断氧化物界面二维电子液体的局面;
5) 首次发现了稀土过渡族金属氧化物界面附近氧化还原反应导致的二维电子液体 (Nano Lett. 2011),打破了国际上盛行的非晶氧化物界面不能形成二维导电的错误认识。
