Signatures of sub-band excitons in few-layer black phosphorus
A. Chaves, G. O. Sousa, K. Khaliji +3
Recent experimental measurements of light absorption in few-layer black phosphorus (BP) reveal a series of high and sharp peaks, interspersed by pairs of lower and broader features…
Plasmonic-based gas sensing with graphene nanoribbons
Kaveh Khaliji, Sudipta Romen Biswas, Hai Hu +5
The main challenge to exploiting plasmons for gas vibrational mode sensing is the extremely weak infrared absorption of gas species. In this work, we explore the possibility of tra…
Plasmons and screening in finite-bandwidth 2D electron gas
Kaveh Khaliji, Tobias Stauber, Tony Low
The dynamical and nonlocal dielectric function of a two-dimensional electron gas (2DEG) with finite energy bandwidth is computed within random-phase approximation. For large bandwi…
Anisotropic Acoustic Plasmons in Black Phosphorus
In-Ho Lee, Luis Martin-Moreno, Daniel A. Mohr +3
Recently, it was demonstrated that a graphene/dielectric/metal configuration can support acoustic plasmons, which exhibit extreme plasmon confinement an order of magnitude higher t…
Tunable plasmon-enhanced birefringence in ribbon array of anisotropic 2D materials
Kaveh Khaliji, Arya Fallahi, Luis Martin-Moreno +1
We explore the far-field scattering properties of anisotropic 2D materials in ribbon array configuration. Our study reveals the plasmon-enhanced linear birefringence in these ultra…
