摘要翻译:
DNA低聚物中的长程电荷转移实验,以及随后测量的--以及非常多样的--固态实验中DNA丝的传输响应,说明需要对基于DNA的天然和人工材料中的电荷迁移有一个彻底的理论理解。在这里,我们对DNA传导的紧结合模型进行了综述,这些模型具有比普通速率方程模型包含更多结构信息的内在优点,同时仍然保留了足够的电子性质细节。这使得对输运性质的模拟相对于密度泛函理论方法或相关第一原理算法更易于管理。

英文摘要:
Long range charge transfer experiments in DNA oligomers and the subsequently measured -- and very diverse -- transport response of DNA wires in solid state experiments exemplifies the need for a thorough theoretical understanding of charge migration in DNA-based natural and artificial materials. Here we present a review of tight-binding models for DNA conduction which have the intrinsic merit of containing more structural information than plain rate-equation models while still retaining sufficient detail of the electronic properties. This allows for simulations of transport properties to be more manageable with respect to density functional theory methods or correlated first principle algorithms.
