Confining two dimensional Dirac fermions on the surface of topological insulators has remained an outstanding conceptual challenge. Here we show that Dirac fermion confinement is achievable in topological crystalline insulators (TCI). which host multiple surface Dirac cones depending on the surface termination and the symmetries it preserves. This confinement is most dramatically refl... https://darthomes.shop/product-category/egg-cups/
