Electrically Tunable Magnetism in Magnetic Topological Insulators
Jing Wang, Biao Lian, Shou-Cheng Zhang
The external controllability of the magnetic properties in topological insulators would be important both for fundamental and practical interests. Here we predict the electric-fiel…
Quantum anomalous Hall effect in magnetic topological insulators
Jing Wang, Biao Lian, Shou-Cheng Zhang
The search for topologically non-trivial states of matter has become an important goal for condensed matter physics. Here, we give a theoretical introduction to the quantum anomalo…
Broadband Linear-Dichroic Photodetector in a Black Phosphorus Vertical p-n Junction
Hongtao Yuan, Xiaoge Liu, Farzaneh Afshinmanesh +12
The ability to detect light over a broad spectral range is central for practical optoelectronic applications, and has been successfully demonstrated with photodetectors of two-dime…
Generation and Electric Control of Spin-Coupled Valley Current in WSe2
Hongtao Yuan, Xinqiang Wang, Biao Lian +8
The valley degree of freedom in layered transition-metal dichalcogenides (MX2) provides the opportunity to extend functionalities of novel spintronics and valleytronics devices. Du…
Spin Liquid Condensate of Spinful Bosons
Biao Lian, Shou-Cheng Zhang
We introduce the concept of a bosonic spin liquid condensate (SLC), where spinful bosons in a lattice form a zero-temperature spin disordered charge condensate that preserves the s…
