Landau levels with magnetic tunnelling in Weyl semimetal and magnetoconductance of ballistic $p$-$n$ junction
David R. Saykin ; Konstantin S. Tikhonov ; Yaroslav I. Rodionov ;
Date 2 Nov 2017
AbstractWe study Landau levels (LLs) of Weyl semimetal (WSM) with two adjacent Weyl nodes. We consider different orientations $eta=angle(mathbf{B},mathbf{k}_0)$ of magnetic field $mathbf{B}$ with respect to $mathbf{k}_0$, the vector of Weyl nodes splitting. Magnetic field facilitates the tunneling between the nodes giving rise to a gap in the transverse energy of the zeroth LL. We show how the spectrum is rearranged at different $eta$ and how this manifests itself in the change of behavior of differential magnetoconductance $dG(B)/dB$ of a ballistic $p$-$n$ junction. Unlike the single-cone model where Klein tunneling reveals itself in positive $dG(B)/dB$, in the two-cone case $G(B)$ is non-monotonic with maximum at $B_c propto Phi_0k_0^2/ln(k_0l_E)$ for large $k_0l_E$, where $l_E=sqrt{hbar v/|e|E}$ with $E$ for built in electric field and $Phi_0$ for magnetic flux quantum.
