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…
Mid-infrared Electro-Optic Modulation in Few-layer Black Phosphorus
Ruoming Peng, Kaveh Khaliji, Nathan Youngblood +3
Black phosphorus stands out from the family of two-dimensional materials as a semiconductor with a direct, layer-dependent bandgap in energy corresponding to the spectral range fro…
