A virtual absorbing layer (VAL) is proposed to achieve low reflection of wave function at the boundary of a graphene sheet. Empirical parameters are tuned to optimize the performance of the VAL. The Klein tunneling effects on a graphene sheet are simulated to confirm the effectiveness of this FDTD scheme and the VAL.Abstract: i;Table of Contents: ii; List of Figures: iv; Acknowledgment: v; Introduction: 1; FDTD Scheme to Solve Dirac-like Equation: 4; Virtual Absorbing Layer (VAL): 14; Simulations on Klein Tunneling: 25; Conclusion: 29; Bibliography: 301976285 bytesapplication/pdf論文公開時間:2016/09/03論文使用權限:同意有償授權(權利金給回饋學校)石墨烯吸收邊界穿隧效應以時域有限差分法及虛擬吸收邊界層模擬石墨烯之克萊因穿隧效應Finite-Difference Time-Domain Method with Virtual Absorbing Layer to Simulate Klein Tunneling on a Graphene Sheetthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/264303/1/ntu-103-R01942080-1.pdf
