Selective generation and amplification of RKKY interactions by P-N interface
Shu-Hui Zhang, Jia-Ji Zhu, Wen Yang +1
We propose a physical mechanism to generate and selectively amplify anisotropic Rudermann-Kittel-Kasuya-Yosida (RKKY) interactions between two local spins. The idea is to combine t…
Tilted Klein tunneling across atomically sharp interfaces
Shu-Hui Zhang, Wen Yang, Kai Chang
Despite many similarities between electronics and optics, the hopping of the electron on a discrete atomic lattice gives rise to energy band nonparabolicity and anisotropy. The cru…
Dirac nodal line metal for topological antiferromagnetic spintronics
Ding-Fu Shao, Gautam Gurung, Shu-Hui Zhang +1
Topological antiferromagnetic (AFM) spintronics is an emerging field of research, which exploits the Néel vector to control the topological electronic states and the associated spi…
Oblique Klein tunneling in 8-Pmmn borophene p-n junctions
Shu-Hui Zhang, Wen Yang
The 8-\textit{Pmmn} borophene is one kind of new elemental monolayer, which hosts anisotropic and tilted massless Dirac fermions (MDF). The planar \textit{p-n} junction (PNJ) struc…
Perfect transmission at oblique incidence by trigonal warping in graphene P-N junctions
Shu-Hui Zhang, Wen Yang
We develop an analytical mode-matching technique for the tight-binding model to describe electron transport across graphene P-N junctions. This method shares the simplicity of the…
Veselago focusing of anisotropic massless Dirac fermions
Shu-Hui Zhang, Wen Yang, F. M. Peeters
Massless Dirac fermions (MDFs) emerge as quasiparticles in various novel materials such as graphene and topological insulators, and they exhibit several intriguing properties, of w…
