论文摘要
我们在这里报告了振荡频率波向量分散的结果，$ω'（k）$，以及对重型GAN样品的表面等离子体声子Polaritons（\ mbox {spphp}）的damping $ω''（k）$。我们表明$ω'（k）$ - 依赖性由三个分支组成，这是由于表面等离子体偏振子（SPP）与表面声子极性（SPHP）的相互作用而具有特定抗骨骼行为的三个分支。发现阻尼$ω''（k）$在抗骨骼区域附近的强烈重新归一化。 $ω'（k）$和$ω''（k）$的分散体用于分析N-GAN谐波反射率光谱的共振行为的精确分析。
We reported here the results of the calculations of wavevector dispersion of oscillations frequencies, $ω'(k)$, and damping $ω''(k)$ of the surface plasmon phonon polaritons (\mbox{SPPhP}) for the heavy-doped GaN sample. We showed that $ω'(k)$- dependence consists of the three branches with the specific anticrossing behavior due to the interaction of surface plasmon polariton (SPP) with surface phonon polariton(SPhP). The strong renormalization of the damping $ω''(k)$ in the vicinity of the anticrossing region was found. The obtained dispersions of the $ω'(k)$ and $ω''(k)$ were applied for the analytical analysis of exact electrodynamic simulation of the resonant behavior of the reflectivity spectrum of the n-GaN grating.
