Recent theories have proposed a concept of valley photonic crystals as an analog of gapped valleytronic materials such as MoS2 and bilayer graphene. Here, we further extend the applicability of valley photonic crystals to surface electromagnetic waves and experimentally demonstrate a valley surface-...
