我们提出了半导体激子的五个主要原因：(1)电子对结合的起源，(2)与附加载流子的相互作用，(3)电子对的量子性质，(4)与光子的耦合，以及(5)光子吸收机制。由于这些差异，我们不应该像通常所做的那样将量子点中的电子-空穴对称为激子；我们建议将其称为Duo。在室内乐的同一框架内，我们同样建议将三个和四个载波称为圆点、三重奏和四重奏，而不是三重奏和双激子。
We present five major reasons why semiconductor exciton, that is, a correlated electron–hole pair in a bulk, quantum well, or quantum wire, is conceptually different from a pair in a quantum dot: (1) the origin of pair binding, (2) the interaction with additional carriers, (3) the quantum nature of the pair, (4) the coupling to photon, and (5) the photon-absorption mechanism. Due to these differences, we should refrain from calling an electron–hole pair in a quantum dot an exciton, as commonly done; we propose to call it a duo. Within the same frame of chamber musics, we likewise propose to call three and four carriers in a dot, a trio and a quatuor, instead of a trion and a biexciton.
