Two‐Dimensional Triferroics: From Fundamental Couplings to Multifunctional Applications

open access: yesAdvanced Science, EarlyView.
This graphic summarizes the three main types of currently reported 2D triferroic couplings. From the structural perspective, existing systems can be broadly classified into two categories, which exhibit distinct symmetry features and coupling behaviors. Beyond the lattice difference, a third type involves the interplay among ferroelectricity, magnetism,

L-mode-edge negative triangularity tokamak (NTT) reactor

open access: yesL-mode-edge negative triangularity tokamak (NTT) reactor
負三角度トカマク(NTT)は除熱第一優先を思想とした新規核融合炉概念である。本論文では、ELMが無いか弱く、大半径部にダイバータを置いたLモード端を保持した負三角度トカマクの炉概念について述べている。また、高い閉じ込め(HH=1.5)を得るか高い磁場(B=15.5T)でNTT核融合炉の主半径は9mから7mに縮めることが可能である。現在の物理課題と技術的実現可能性を議論している。

Deciphering Short‐Range Order in 2D Transition Metal Dichalcogenides: From Origin to Multi‐Scale Property Modulation

open access: yesAdvanced Science, EarlyView.
Short‐range order in 2D transition metal dichalcogenides is revealed as a new design paradigm. Driven by chemical affinity and atomic size, it governs properties across scales. Weak ordering tunes site‐resolved magnetism and d‐band centers, while strong ordering eliminates gap states to open band gaps.

Single Null Negative Triangularity Tokamak for Power Handling

open access: yesSingle Null Negative Triangularity Tokamak for Power Handling
原型炉においては、これまでを大きく上回る除熱が必要であり、そのために高い密度のSOLが必要になる。そのような場合、従来の密度限界近傍でのHモード閉じ込め劣化と同様な現象が起こる可能性がある。このために、Hモードに頼らない運転シナリオを考慮しておくことはバックアッププランとして重要である。この観点から負三角度トカマクの可能性を評価比較する。本配位でのTCVダイバータ実験はLモードエッジでありながらHモード閉じ込め性能を確保しており、DIII-Dでの初期結果も同様の結果が得られている。 59th Annual Meeting of the APS Division of Plasma ...

Buried Unstrained Germanium Channels: A Lattice‐Matched Platform for Quantum Technology

open access: yesAdvanced Science, EarlyView.
ABSTRACT Strained germanium (ε$\varepsilon$‐Ge) and strained silicon (ε$\varepsilon$‐Si) buried quantum wells have enabled advanced spin‐qubit quantum processors. However, in the absence of suitable lattice‐matched substrates, ε$\varepsilon$‐Ge and ε$\varepsilon$‐Si are deposited on defective, metamorphic SiGe buffers, which may impact device ...

Artificial Piezoelectric Interface Enables Ultrafast Interfacial Ion Kinetic for Highly‐Sensitive Piezoionic Sensors

open access: yesAdvanced Science, EarlyView.
This study proposes a piezoelectric interface modification strategy to amplify the piezoionic effect. The piezoelectric interface generates an intrinsic electric field, which not only drives rapid ion migration but also concentrates polarized ions on the interface. The flexible sensor delivers superior performance, such as a quick response rate, strong

Defect‐Functionalization‐Mediated Tunneling Drives Nonlinear Photoemission in Perovskites

open access: yesAdvanced Science, EarlyView.
This cover illustration depicts CsPbBr3 perovskite nanocrystals embedded with functionalized defect vacancies, where electrons migrate through defect‐mediated pathways and emit as lightning‐like beams. The imagery visualizes the core discovery of our work—defect‐functionalization‐mediated tunneling enabling nonlinear photoemission, where deep‐level ...
