Multinary Alloying Suppresses Defect Formation in Emerging Inorganic Solar Cells
Jiangjian Shi, Jinlin Wang, Fanqi Meng +10
The Cu2ZnSn(S, Se)4 (CZTSSe) emerging inorganic solar cell is highly promising for accelerating the large-scale and low-cost applications of thin-film photovoltaics. It possesses d…
Spin State Disproportionation in Insulating Ferromagnetic LaCoO3 Epitaxial Thin Films
Shanquan Chen, Jhong-Yi Chang, Qinghua Zhang +14
The origin of insulating ferromagnetism in epitaxial LaCoO3 films under tensile strain remains elusive despite extensive research efforts have been devoted. Surprisingly, the spin…
Room-temperature ferromagnetism at an oxide/nitride interface
Qiao Jin, Zhiwen Wang, Qinghua Zhang +26
Heterointerfaces have led to the discovery of novel electronic and magnetic states because of their strongly entangled electronic degrees of freedom. Single-phase chromium compound…
Dynamics of anisotropic oxygen-ion migration in strained cobaltites
Qinghua Zhang, Fanqi Meng, Ang Gao +13
Orientation control of oxygen vacancy channel (OVC) is a highly desirable for tailoring oxygen diffusion as it serves fast transport channel in ion conductors, which is widespread…
Exchange coupling in synthetic anion-engineered chromia heterostructures
Shan Lin, Zhiwen Wang, Qinghua Zhang +15
Control of magnetic states by external factors has garnered a mainstream status in spintronic research for designing low power consumption and fast-response information storage and…
Near-Room Temperature Ferromagnetic Insulating State in Highly Distorted LaCoO2.5 with CoO5 Square Pyramids
Qinghua Zhang, Ang Gao, Fanqi Meng +9
Dedicated control of oxygen vacancies is an important route to functionalizing complex oxide films. It is well-known that tensile strain significantly lowers the oxygen vacancy for…
Realization of AlSb in the double layer honeycomb structure: a robust new class of two-dimensional material
Le Qin, Zhi-Hao Zhang, Zeyu Jiang +10
Exploring new two-dimensional (2D) van der Waals (vdW) systems is at the forefront of materials physics. Here, through molecular beam epitaxy on graphene-covered SiC(0001), we repo…
Overlooked transportation anisotropies in d-band correlated rare-earth perovskite nickelates
Jikun Chen, Haiyang Hu, Fanqi Meng +7
Anisotropies in electronic transportations conventionally originate from the nature of low symmetries in crystal structures, and were not anticipated for perovskite oxides, the cry…
Ultrafast dynamic conductivity and scattering rate saturation of photoexcited charge carriers in silicon investigated with a midinfrared continuum probe
Fanqi Meng, Mark D. Thomson, Bo E. Sernelius +2
We employ ultra-broadband terahertz-midinfrared probe pulses to characterize the optical response of photoinduced charge-carrier plasmas in high-resistivity silicon in a reflection…
