Coherent direction-dependent valley transport in Dirac/Weyl semimetals
Can Yesilyurt
We investigate the coherent transmission of collimated wave packets through an inversion-asymmetric electrostatic barrier in a Dirac or Weyl channel. For a barrier consisting of a…
Parabolic-Cylinder Approach to Valley-Polarized Conductance in Tilted Anisotropic Dirac-Weyl Systems

We demonstrate quantum dot (QD) formation in three-dimensional Dirac semimetal CdAs nanowires using two electrostatically tuned pn junctions with a gate and magnetic…
Strain-controlled valley and spin separation in silicene heterojunctions
Yuan Li, H. B. Zhu, G. Q. Wang +8
We adopt the tight-binding mode-matching method to study the strain effect on silicene heterojunctions. It is found that valley- and spin-dependent separation of electrons cannot b…

Influence of Fermi arc states and double Weyl node on tunneling in a Dirac semimetal
Zhuo Bin Siu, Can Yesilyurt, Mansoor B. A. Jalil +1
Most theoretical studies of tunneling in Dirac and the closely related Weyl semimetals have modeled these materials as single Weyl nodes described by the three-dimensional Dirac eq…
Klein tunneling in Weyl semimetals under the influence of magnetic field
Can Yesilyurt, Seng Ghee Tan, Gengchiau Liang +1
Klein tunneling refers to the absence of normal backscattering of electrons even under the case of high potential barriers. At the barrier interface, the perfect matching of electr…
