在标度体系下研究了单层石墨烯的电动力学行为。在任意有限温度下，存在一个弱阻尼的集体热等离子体极化激元模，其色散和与波长相关的阻尼被解析地确定。与这种模式相关的电场和磁场在垂直于石墨烯层的方向上呈指数衰减，但是，与金属的表面等离子体极化激元模式不同，衰减长度和模式频率强烈依赖于温度。这可能导致产生和操纵这些模式的新方法。
The electrodynamics of single-layer graphene is studied in the scaling regime. At any finite temperature, there is a weakly damped collective thermoplasma polariton mode whose dispersion and wavelength-dependent damping is determined analytically. The electric and magnetic fields associated with this mode decay exponentially in the direction perpendicular to the graphene layer, but, unlike the surface plasma polariton modes of metals, the decay length and the mode frequency are strongly temperature-dependent. This may lead to new ways of generation and manipulation of these modes.
