论文摘要
我们为理想的多扬环开发了一个分析模型，该模型描述了由于鲜明效应而导致分子谱中诱导的THZ间隙。这个简单的模型也可以用来描述一种奇数的环碳，该环碳经历了自发性对称事件（由于Jahn-Teller效应）作为跨理想环上的有效偶极子。我们表明，差距的大小和跨越光学转变的强度都可以通过改变外部电场强度来调节。提出了基于光激发的THZ发射方案，从而为基于Cyclo [n]碳的新型THZ发射器铺平了道路。
We develop an analytic model for an ideal polyyne ring which describes the induced THz gap in the molecular spectrum due to the Stark effect. This simple model can also be used to describe an odd-dimered cyclocarbon which has undergone a spontaneous symmetry-breaking event (due to the Jahn-Teller effect) as an effective dipole across an ideal ring. We show that both the size of the gap, and the strength of optical transitions across it, can be modulated by varying the external electric field strength. A THz emission scheme based on optical excitation is proposed, thus paving the way for a new class of THz emitters based on cyclo[n]carbon.
