Terahertz photocurrent probe of quantum geometry and interactions in magic-angle twisted bilayer graphene
Roshan Krishna Kumar, Geng Li, Riccardo Bertini +24
Moiré materials represent strongly interacting electron systems bridging topological and correlated physics. Despite significant advances, decoding wavefunction properties underlyi…
Electrostatic control of nonlinear photonic-crystal polaritons in a monolayer semiconductor
Ekaterina Khestanova, Vanik Shahnazaryan, Valerii K. Kozin +6
Integration of 2D semiconductors with photonic crystal slabs provides an attractive approach to achieve strong light--matter coupling and exciton-polariton formation in a planar ch…
Robustness of momentum-indirect interlayer excitons in MoS2/WSe2 heterostructure against charge carrier doping
Ekaterina Khestanova, Tatyana Ivanova, Roland Gillen +13
Monolayer transition-metal dichalcogenide (TMD) semiconductors exhibit strong excitonic effects and hold promise for optical and optoelectronic applications. Yet, electron doping o…
Experimental observation of topological exciton-polaritons in transition metal dichalcogenide monolayers
Mengyao Li, Ivan Sinev, Fedor Benimetskiy +11
The rise of quantum science and technologies motivates photonics research to seek new platforms with strong light-matter interactions to facilitate quantum behaviors at moderate li…
Spin-valley dynamics in alloy-based transition metal dichalcogenide heterobilayers
V. Kravtsov, A. D. Liubomirov, R. V. Cherbunin +11
Van der Waals heterobilayers based on 2D transition metal dichalcogenides have been recently shown to support robust and long-lived valley polarization for potential valleytronic a…
Nonlinear polaritons in monolayer semiconductor coupled to optical bound states in the continuum
V. Kravtsov, E. Khestanova, F. A. Benimetskiy +16
Optical bound states in the continuum (BICs) provide a way to engineer very narrow resonances in photonic crystals. The extended interaction time in such systems is particularly pr…
Strained bubbles in van der Waals heterostructures as local emitters of photoluminescence with adjustable wavelength
Anastasia Tyurnina, Denis Bandurin, Ekaterina Khestanova +6
The possibility to tailor photoluminescence (PL) of monolayer transition metal dichalcogenides (TMDCs) using external factors such as strain, doping and external environment is of…
High-temperature quantum oscillations caused by recurring Bloch states in graphene superlattices
R. Krishna Kumar, X. Chen, G. H. Auton +13
Cyclotron motion of charge carriers in metals and semiconductors leads to Landau quantization and magneto-oscillatory behavior in their properties. Cryogenic temperatures are usual…
Graphene bubbles on a substrate : Universal shape and van der Waals pressure
E. Khestanova, F. Guinea, L. Fumagalli +2
Trapped substances between a 2D crystal, such as graphene, and an atomically flat substrate, for example, hexagonal boron nitride, give rise to the formation of bubbles. We show th…
Magnetotransport in single layer graphene in a large parallel magnetic field
F. Chiappini, S. Wiedmann, M. Titov +7
Graphene on hexagonal boron-nitride (h-BN) is an atomically flat conducting system that is ideally suited for probing the effect of Zeeman splitting on electron transport. We demon…
Quality heterostructures from two dimensional crystals unstable in air by their assembly in inert atmosphere
Y. Cao, A. Mishchenko, G. L. Yu +16
Many layered materials can be cleaved down to individual atomic planes, similar to graphene, but only a small minority of them are stable under ambient conditions. The rest reacts…
