Counterdirectional Exciton and Trion Motion in Applied Electric Field
Daniel Vaz, Yuanjun Guan, Qiaochu Wan +13
Charged excitonic complexes are central to the optoelectronic and many-body properties of semiconductors, yet their real-space transport dynamics remain largely unexplored. Here, w…
Hexagonal Boron Nitride Spin Defects for Quantum Photonics: Annealing-Free Generation by Krypton Ion Implantation
Ikshvaku Shyam, Raj Singh, Mangababu Akkanaboina +11
Controlled, reproducible generation of luminescent defect centres in hBN remains a key challenge for scalable quantum-photonic technologies. Here, we report Kr ion implantati…
C-band 160 Gbs-1 Zero-bias Graphene Photodetectors: Breaking the Responsivity-Bandwidth Trade-off by Heterostructure Engineering
Karuppasamy Pandian Soundarapandian, Alberto Montanaro, Ioannis Vangelidis +17
Graphene photodetectors offer ultrafast response and broadband operation, but their responsivity is typically limited by rapid hot-carrier cooling, leading to a trade-off between s…
Ultrafast Nano-Imaging and Optical Control of Hyperbolic Phonon Polaritons at hBN/WS Heterojunctions
Kazuki Kamada, Keisuke Shinokita, Fanyu Zeng +7
Manipulating nanoscale light-matter interactions on ultrafast time scales is indispensable for future polaritonic devices. Hyperbolic phonon polaritons (HPhPs) in van der Waals mat…
Surface defects in carbon-doped hexagonal boron nitride for negative-contrast direct laser writing
Dmitrii Litvinov, Virgil Gavriliuc, Magdalena Grzeszczyk +5
Radiative defects in hexagonal boron nitride (hBN) are active in a broad spectral range from deep ultraviolet to near-infrared wavelengths. Representatives of these defects act as…
Polariton-mediated binding of anti-aligned dipolar excitons
Haifeng Kang, Quanbing Guo, Tianyi Zhou +7
Interacting bosonic quasiparticles are the cornerstone for exploring many-body physics and nonlinear quantum phenomena in correlated light-matter systems. Strongly interacting dipo…
Electrically reconfigurable dipolar polaritons with highly tunable nonlinearity in a homobilayer microcavity
Baixu Xiang, Yubin Wang, Guihan Wen +9
Active control over optical nonlinearity in solid-state systems is central to unlocking exotic many-body phenomena and photonic devices. While exciton-polaritons in transition meta…
