We investigated the dimensionality transition behavior of graphene localized plasmon resonances in confinement-controlled graphene devices. We first demonstrated a possibility of dimensionality transition, based on the devices carrier-density dependence, from a two-dimensional plasmon resonance to a one-dimensional plasmon one. We fabricated optical transparent devices and electrical transport devices on the same optical transparent wafer. These devices allow detailed control and analysis between carrier density and plasmon resonance peak positions. The carrier density from (two-dimensional) to constant (one-dimensional) is consistent with the theoretical predictions based on the Dirac Fermion carriers in linear-band structure materials.

我们研究了限制控制的石墨烯器件中石墨烯局域等离子体共振的维数跃迁行为。我们首先证明了基于器件载流子密度依赖性的维数转换的可能性，从二维等离子体共振到一维等离子体共振。我们在同一个光学透明晶片上制造了光学透明器件和电传输器件。这些设备允许在载流子密度和等离子体共振峰位置之间进行详细控制和分析。从（二维）到常数（一维）的载流子密度与基于线性带结构材料中狄拉克费米子载流子的理论预测一致。
