我们提出了一个本地化的量子点状态和填充连续之间的杂交的光学签名。带负电荷的三电子在一个量子点中的辐射复合留下一个电子，我们证明了在两个垂直电场区域中，电子通过隧穿相互作用与一个连续体杂交。杂交表现出自己通过一个不寻常的电压依赖性的发射能量和非洛伦兹线的形状，功能，我们再现与理论的基础上的安德森哈密顿。
We present an optical signature of a hybridization between a localized quantum dot state and a filled continuum. Radiative recombination of the negatively charged trion in a single quantum dot leaves behind a single electron. We show that in two regions of vertical electric field, the electron hybridizes with a continuum through a tunneling interaction. The hybridization manifests itself through an unusual voltage dependence of the emission energy and a non-Lorentzian line shape, features which we reproduce with a theory based on the Anderson Hamiltonian.
