Ultrastrong coupling of topologically protected edge and bulk magnetoplasmons without a dedicated cavity
F. Velli, P. Sai, M. Dub +6
In the ultrastrong light-matter coupling regime, the ability to confine the electric field to subwavelength scales and define an electromagnetic mode is essential. This task is typ…
Potential of Graphene/AlGaN/GaN heterostructures to study the drag and two-stream instability effects
A. Rehman, D. B. But, P. Sai +6
Graphene/AlGaN/GaN heterostructures are proposed to investigate the drag and two-stream instability effects. In this study, graphene grown by chemical vapor deposition was transfer…
Effect of current on terahertz plasmons in AlGaN/GaN heterostructures
M. Dub, P. Sai, Y. Ivonyak +3
Terahertz transmittance spectra of plasmonic crystals based on two-dimensional electron gas in AlGaN/GaN heterostructures were studied in grating-gate and gateless plasmonic crysta…
Effect of temperature on 2D terahertz plasmons and electron effective mass in AlGaN/GaN
M. Dub, P. Sai, D. Yavorskiy +6
The effect of temperature on two-dimensional plasmons in large-area AlGaN/GaN plasmonic crystals was studied experimentally. With the temperature increase the resonant plasmon freq…
Extreme Terahertz Nonlinearity of AlGaN/GaN-based Grating-Gate Plasmonic Crystals
Pavlo Sai, Vadym V. Korotyeyev, Dmytro B. But +12
We present a novel approach to enhance THz nonlinearity by the resonant excitation of two-dimensional plasmons in grating-gate plasmonic crystals. Using a high-electric-field THz p…
Pressure tuning of HgCdTe epitaxial layers -- the role of the highly disordered buffer layer
D. Yavorskiy, Y. Ivonyak, D. But +9
HgCdTe alloys are unique because by increasing the Cd content x, one modifies the band structure from inverted to normal, which fundamentally modifies the dispersion of bulk and su…
Strong transient magnetic fields induced by THz-driven plasmons in graphene disks
Jeong Woo Han, Pavlo Sai, Dmytro But +10
Strong circularly polarized excitation opens up the possibility to generate and control effective magnetic fields in solid state systems, e.g., via the optical inverse Faraday effe…
Electrical Tuning of Terahertz Plasmonic Crystal Phases
P. Sai, V. V. Korotyeyev, M. Dub +9
We present an extensive study of resonant two-dimensional (2D) plasmon excitations in grating-gated quantum well heterostructures, which enable an electrical control of periodic ch…
Beatings of ratchet current magneto-oscillations in GaN-based grating gate structures: manifestation of spin-orbit band splitting
P. Sai, S. O. Potashin, M. Szola +8
We report on the study of the magnetic ratchet effect in AlGaN/GaN heterostructures superimposed with lateral superlattice formed by dual-grating gate structure. We demonstrate tha…
