Surface effects on the plasmons in two-dimemsional heterostructures: Application to tilted semi-Dirac materials
Teresa Lee, Godfrey Gumbs, Thi Nga Do +2
We derived closed-form analytic expressions for the plasmon dispersion equations for two and three monolayers embedded in a non-uniform dielectric medium with a surface. There is n…
Flat bands of TaS under superlattice potential modulation: A Wannier tight-binding model study
Thi-Nga Do, Godfrey Gumbs
In this work, we construct a Wannier tight-binding model for TaS under a superlattice potential modulation, based on the Joint Automated Repository for Various Integrated Simul…
Magnetoplasmons in magic-angle twisted bilayer graphene
Thi-Nga Do, Po-Hsin Shih, Godrey Gumbs
The magic-angle twisted bilayer graphene (MATBLG) has been demonstrated to exhibit exotic physical properties due to the special flat bands. However, exploiting the engineering of…
Strain Engineering of Magneto-optical Properties in CB/CN van der Waals Heterostructure
Po-Hsin Shih, Thi-Nga Do, Godfrey Gumbs
Carbon-based bilayer van der Waals (vdW) materials are attracting much attention due to their predicted interesting physical properties. Here, we theoretically investigate electron…
Quantized Hall current in topological nodal-line semimetal
Po-Hsin Shih, Thi-Nga Do, Godfrey Gumbs +3
Photocurrent acts as one of measurable responses of material to light, which has proved itself to be crucial for sensing and energy harvesting. Topological semimetals with gapless…
Generalized Peierls substitution for the tight-binding model of twisted multilayer graphene in a magnetic field
Thi-Nga Do, Po-Hsin Shih, Hsin Lin +3
We propose a generalized Peierls substitution method in conjunction with the tight-binding model to explore the magnetic quantization and quantum Hall effect in twisted multilayer…
