基于非平衡格林函数的量子输运退相模型

Non-equilibrium Green s function based model for dephasing in quantum transport

Roksana Golizadeh-Mojarad, Supriyo Datta

摘要:

本文的目的是描述一个简单的唯象方法,包括在量子输运模型中的非相干退相过程。所提出的说明性的数值结果表明,该模型提供了灵活的调整程度的相位和动量弛豫独立的介观物理学和器件模拟中目前还没有,同时保持其他唯象模型的简单性。

英文摘要:

The objective of this paper is to describe a simple phenomenological approach for including incoherent dephasing processes in quantum transport models. The presented illustrative numerical results show this model provides the flexibility of adjusting the degree of phase and momentum relaxation independently that is not currently available in mesoscopic physics and in device simulations while retaining the simplicity of other phenomenological models.
