Mechanism of magnetic diode in artificial honeycomb lattice

George Yumnam, Jiasen Guo, Yiyao Chen +8

Spin diode is important prerequisite to practical manifestation of spin electronics. Yet, a functioning magnetic diode at room temperature is still illusive. Here, we reveal diode-…

Photoinduced iodide repulsion and halides-demixing in layered perovskites

Yongtao Liu, Miaosheng Wang, Anton V. Ievlev +3

Mixing halides in metal halide perovskites (MHPs) is an effective approach to adjust MHPs bandgap for applications in tandem solar cells. However, mixed-halide (MH-) MHPs undergo l…

Quantum disordered state of magnetic charges in nanoengineered honeycomb lattice

George Yumnam, Yiyao Chen, Jiasen Guo +3

A quantum magnetic state due to magnetic charges is never observed, even though they are treated as quantum mechanical variable in theoretical calculations. Here, we demonstrate th…
