AI 中文摘要
我们研究石墨烯莫尔体系中局域态与传播型一维（1D）模式的共存现象。首先，在最小模型框架内证明，空间变化的标量势可束缚局域态，而交错势的符号变化会沿产生的畴壁生成1D模式，这两类态可在同一有限能量窗口内共存，形成混合网络。随后，我们展示该机制在扭曲单层-菱面N层石墨烯中的微观实现：在真实参数范围内获得的能带结构、等能线与布洛赫波函数，揭示了局域近平带态与传播型准一维模式的共存。本研究结果确立了扭曲单层-菱面石墨烯作为实现具有不同有效维度态共存的混合电子网络的有前景平台。
英文摘要
We investigate the coexistence of localized states and propagating one-dimensional (1D) modes in graphene moiré systems. We first show within a minimal model that a spatially varying scalar potential can confine localized states, while sign changes of a staggered potential generate 1D modes along the resulting domain walls. These two types of states can coexist within the same finite energy window and form a hybrid network. We then demonstrate a microscopic realization of this mechanism in twisted monolayer-rhombohedral N-layer graphene. Band structures, energy contours, and Bloch wave functions obtained in a realistic parameter regime reveal the coexistence of localized nearly flat-band states and propagating quasi-1D modes. Our results establish twisted monolayer-rhombohedral graphene as a promising platform for realizing hybrid electronic networks with coexisting states of distinct effective dimensionalities.
