二维材料中的激发态介子

Excited-State Trions in Two Dimensional Materials

Jun Jan, Kalman Varga

摘要:

利用复标度法和稳定化方法,结合随机变分方法,我们证明了电子和空穴通过屏蔽库仑相互作用的二维三粒子系统中存在窄的共振态.这些共振是由激发态激子和围绕它们的第三个粒子组成的松散束缚系统。这些共振态可以用来解释和鉴别最近的激发态实验研究。

英文摘要:

Using the complex scaling and the stabilization method combined with the stochastic variational approach, we have shown that there are narrow resonance states in two-dimensional three particle systems of electrons and holes interacting via screened Coulomb interaction. These resonances are loosely bound systems of excited state excitons with a third particle circling around them. Recent experimental studies of excited state trions might be explained and identified by these resonant states.
