摘要:
本文旨在从理论上分析倾斜 Dirac 锥材料中 Dirac 费米子的行为,特别是那些已经扩散越过势垒的费米子。我们的结果表明,y 方向上的倾斜程度可导致 Dirac 费米子束相对于 Fermi 面和约束面呈现不同的准直。为研究透射概率,我们对所得结果进行了数值计算,考虑了系统的各种构型以及不同的外部和内部物理参数,并通过表征所提出异质结构中费米子输运的行为来实现这一点。我们的发现为开发利用 Dirac 费米子准直的可控电子器件奠定了基础;这种准直受倾斜参数控制,可实现精确操控和增强的功能。
英文摘要:
This paper aims to theoretically analyze the behavior of Dirac fermions in tilted Dirac cone material, particularly those that have diffused a barrier potential.Our results show that the degree of tilt in the y-direction can lead to different collimations of the Dirac fermion beams relative to the Fermi and confinement surfaces. To study the transmission probability, we exploited our results numerically, taking into account the various configurations of the system and the different external and internal physical parameters by characterizing the behavior of fermionic transport in a proposed heterostructure. Our findings lay the groundwork for developing controllable electronic devices utilizing Dirac fermion collimation, governed by the tilt parameter, enabling precise manipulation and enhanced functionality.
