Broadband strong optical dichroism in topological Dirac semimetals with Fermi velocity anisotropy
J. Lim, K. J. A. Ooi, C. Zhang +2
Prototypical three-dimensional (3D) topological Dirac semimetals (DSMs), such as CdAs and NaBi, contain electrons that obey a linear momentum-energy dispersion with dif…
Fractional Fresnel coefficients for optical absorption in femtosecond laser-induced rough metal surfaces
Muhammad Zubair, Yee Sin Ang, Kelvin J. A. Ooi +1
The surface morphology of metal influences its optical absorptivity. Recent experiments have demonstrated that the femtosecond laser induced surface structures on metals could be d…
Generalized Fowler-Nordheim field-induced vertical electron emission model for two-dimensional materials
Yee Sin Ang, M. Zubair, K. J. A. Ooi +1
Current theoretical description of field-induced electron emission remains mostly bounded by the classic Fowler-Nordheim (FN) framework developed nearly one century ago. For the em…
Efficiencies of Aloof-Scattered Electron Beam Excitation of Metal and Graphene Plasmons
Kelvin J. A. Ooi, Wee Shing Koh, Hong Son Chu +2
We assessed the efficiencies of surface plasmon excitation by an aloof-scattered electron beam on metals and graphene. Graphene is shown to exhibit high energy transfer efficiencie…
