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…
Autonomous robotic mechanical exfoliation of two-dimensional semiconductors combined with Bayesian optimization
Fan Yang, Wataru Idehara, Kenya Tanaka +3
Simple mechanical exfoliation of layered materials is the most frequently employed method for producing high-quality monolayers of two-dimensional semiconducting materials. However…
Lattice-guided growth of dense arrays of aligned transition metal dichalcogenide nanoribbons with high catalytic reactivity
Zongpeng Ma, Pablo Solís-Fernández, Kaito Hirata +15
Transition metal dichalcogenides (TMDs) exhibit unique properties and potential applications when reduced to one-dimensional (1D) nanoribbons (NRs), owing to quantum confinement an…
180-twisted bilayer ReSe as an artificial noncentrosymmetric semiconductor
S. Akatsuka, M. Sakano, T. Yamamoto +18
We have fabricated a 180-twisted bilayer ReSe by stacking two centrosymmetric monolayer ReSe flakes in opposite directions, which is expected to lose spatial invers…
Quantum coherence and interference of a single moiré exciton in nano-fabricated twisted semiconductor heterobilayers
Haonan Wang, Heejun Kim, Duanfei Dong +4
Moiré potential acts as periodic quantum confinement for optically generated exciton, generating spatially ordered zero-dimensional quantum system. However, broad emission spectrum…
Dynamics of moire trion and its valley polarization in microfabricated WSe2/MoSe2 heterobilayer
Heejun Kim, Duanfei Dong, Yuki Okamura +4
The moire potential, induced by stacking two monolayer semiconductors with slightly different lattice mismatches, acts as periodic quantum confinement for optically generated excit…
Moiré exciton dynamics and moiré exciton-phonon interaction in a WSe/MoSe heterobilayer
Keisuke Shinokita, Yuhei Miyauchi, Kenji Watanabe +2
Moiré patterns with angular mismatch in van der Waals heterostructures composed of atomically thin semiconducting materials are a fascinating platform to engineer the optically gen…
Exciton diffusion in a hBN-encapsulated monolayer MoSe2
T. Hotta, S. Higuchi, A. Ueda +7
Excitons, quasi particles composed of an electron and a hole, play an important role in optical responses in low-dimensional nanostructures. In this work, we have investigated exci…
