We argue that the Kratzer potential is unsuitable for the description of an electron in a spherical quantum dot. We show that the authors failed to derive the correct interaction between the electron and the electric field. Besides, they omitted a term in the interaction between the electron and the magnetic field that does not appear to be negligible.

评论“球形量子点的电子结构：克拉策势、氢杂质、外部电场和磁场的影响”

我们认为 Kratzer 势不适合描述球形量子点中的电子。我们表明作者未能推导出电子和电场之间的正确相互作用。此外，他们在电子和磁场之间的相互作用中省略了一个似乎不可忽略的术语。
