Outline of Research at the Start

パッチ粒子は,パッチ由来の異方的相互作用により特異な構造を形成し,フォトニック結晶などの素材として期待されている。パッチ粒子が作る構造の研究は進みつつあるが,形成過程の理解は不十分である。さらに,パッチ粒子は必ずしも球形とは限らず,パッチによる異方性と粒子形状による異方性が混在している場合がある。そこで,本研究では,パッチによる相互作用の異方性と粒子が球状ではなくなることによる粒子形状の異方性がパッチ粒子の作る構造に与える影響に着目する。パッチ粒子の構造形成過程をシミュレーションにより明らかにするとともに,実験により巨大良質結晶の作成を試みる。

Outline of Final Research Achievements

Patchy particles form unique structures due to patch-derived anisotropic interactions and are anticipated as materials for photonic crystals.While research on the structures formed by patchy particles is advancing, the understanding of the formation process remains incomplete. Furthermore, patchy particles are not necessarily spherical, as there may be a mixture of anisotropy from patches and anisotropy from particle shape. Therefore, this study focuses on the impact of the anisotropy of interactions due to patches and the anisotropy of particle shape resulting from non-spherical particles on the structures formed by patchy particles. We aim to elucidate the structure formation process of patchy particles through simulations and attempt to create large, high-quality crystals through experimentation

Academic Significance and Societal Importance of the Research Achievements

コロイド粒子は,波長程度の大きさを持つことからフォトニック結晶の材料として期待されている。特に,ダイヤモンド構造が完全フォトニックバンドを持つ構造を形成することができることから,いかにダイヤモンド構造を形成するかが目下の課題の一つである。パッチ粒子は,パッチの数や位置を制御することにより,様々な構造を作成することが可能であり,容易に求められる構造を作れる可能性がある。本研究は,パッチ粒子を利用したフォトニック結晶の基礎研究として非常に重要である。
