DOI: 10.1088/1402-4896/acd0dd
Abstract: In this work, a photonic valley-locked heterostructure is proposed, which is composed of a Dirac photonic crystal (DPC) and two valley photonic crystals (VPC), with opposite valley Chern numbers. By modifying the size of rods… read more here.

DOI: 10.1103/physrevb.97.085410
Abstract: Silicene and germanene, as graphenelike materials with observable spin-orbit couplings and two distinctive valleys, have potential applications in future low-dissipation spintronics and valleytronics. We here propose a magnetic system of silicene or germanene intercalated between… read more here.
