摘要: 我们研究了在微波场作用下单层石墨烯势阱结构的透射几率、电导、散粒噪声、Fano因子随含时周期势强度和系统结构参数(入射能量、势垒宽度)的变化规律。我们发现，由于微波场的存在，系统的电导、散粒噪声和Fano因子将会被增强。同时，我们可以通过调制含时周期势的强度和系统的结构参数来控制电子的输运。我们希望这些工作能够对以单层石墨烯为基础的电子仪器的设计提供有价值的参考。
Abstract: We investigated the transport properties of Dirac electrons in monolayer graphene-based well structures with microwave fields. We have undertaken a numerical calculate and analyze of the transmission probabilities, angularly averaged conductivity, shot noise, and Fano factor of the system as the external field strength, incident energy and the well width are changed. The results re-veal that the presence of external field makes they are improved and show peculiar behavior. One can modulate the transport of carriers by adjusting the microwave field strength and the structure parameters. We hope that these works can provide valuable reference for the design of single layer graphene based electronic instruments.
