Defect Driven Electronic Structure Reconfiguration and Hierarchical Phonon Suppression in Ag2Se Thermoelectrics

Advanced Science, EarlyView.
Indium substitution in Ag2Se nanocrystals simultaneously tailors electronic structure and lattice dynamics. Fermi‐level upshift and band‐gap narrowing enhance electrical transport, while defect‐induced lattice softening intensifies phonon scattering and suppresses lattice thermal conductivity.

Theory of Three-Dimensional Sound Field Reproduction

IEICE ESS Fundamentals Review, 2009
臨場感の高い音響を実現するため，様々な音場再生技術が研究開発されている．これらは，心理音響モデルに基づく方式と，物理音響モデルに基づく方式に大別できる．前者としては，5.1サラウンドから22.2マルチチャネル音響に至る様々な方式が提案されている．いずれも，2チャネルステレオの音像制御方式を基本としており，チャネル数を増やすことで，音場再生能力を向上させている．一方，後者は，音の物理量再現を目的とした方式であり，Wave Field Synthesisや境界音場制御法など，音の場の再現を目指す方式と，アンビソニックスに代表される，受音点での音の物理量を再現する方式に分けることができる．本稿では，これらの方式の基本技術を概観するとともに，その背景となる理論を紹介する．

Coupled Vacancy and Phonon‐Scattering Engineering Drive Defect Evolution Toward Multifunctional High‐Performance Bi2Te3 Thermoelectrics

Advanced Science, EarlyView.
ZnSb reduces carrier concentration and suppresses Te volatilization, while Se substitution within QLs softens phonons and enhances anharmonicity. Swapped bilayers near twin boundaries strengthen phonon scattering and interlayer bonding. As a result, the optimal sample achieves an ultra‐high zT ∼1.51, cooling temperature difference of ∼70 K, power ...

Sound-field reproduction systems using fixed-directivity loudspeakers

, 2010
Sound reproduction systems using open arrays of loudspeakers in rooms suffer from degradations due to room reflections. These reflections can be reduced using pre-compensation of the loudspeaker signals, but this requires calibration of the array in the ...
