论文摘要
一个典型的石墨烯异质结构可以分为两个经典区域,在该区域中,运输基本上是扩散的,由“量子活性区域”(例如局部封闭的区域)隔开,电荷载体根据量子力学的定律散布,在本文中,我们在本文中进行了量子方程式,在此中,量子范围是量子的量子,并在其中描述了量子的量子,并在其中描述了量子的数学模型,是在其中的数学范围,是在其中的数学区域,是在其中的数学区域,是段落的量子,是在其中的数学区域,是在其中的数学范围,是在其中的数学范围,是在其中划分的阶段。施加的传输条件考虑了量子散射过程。数值模拟与实验数据表现出良好的一致性。
A typical graphene heterojunction device can be divided into two classical zones, where the transport is basically diffusive, separated by a "quantum active region" (e.g., a locally gated region), where the charge carriers are scattered according to the laws of quantum mechanics.In this paper we derive a mathematical model of such a device, where the classical regions are described by drift-diffusion equations and the quantum zone is seen as an interface where suitable transmission conditions are imposed that take into account the quantum scattering process. Numerical simulations show good agreement with experimental data.
