福原幸平教授の研究室では、有機カルシウムトランスポーターの分子機能解明と、非晶質半導体におけるトポロジカル電子状態の発見を柱としています。特に、脳由来の新規トランスポーターOATP-Eの同定や、Fe-Sn系非晶質薄膜における量子異常ホール効果の起源解明が進んでいます。また、磁性Weyl半金属Co₃Sn₂S₂の高品質薄膜作製とそのトポロジカル物性の評価も重要な研究テーマです。

We have recently identified that rat organic anion transporters, polypeptide2 (oatp2) and oatp3, both of which transport thyroid hormones. However, in humans the molecular organization of the organic anion transporters has diverged, and the responsible molecule for thyroid hormone transport has not been clarified, except for human liver-specific transporter (LST-1) identified by us. In this study we isolated and characterized a novel human organic anion transporter, OATP-E from human brain. The
Amorphous semiconductors are widely applied to electronic and energy-conversion devices owing to their high performance and simple fabrication processes. The topological concept of the Berry curvature is generally ill-defined in amorphous solids, due to the absence of long-range crystalline order. Here, we demonstrate that the Berry curvature in the short-range crystalline order of kagome-lattice fragments effectively contributes to the anomalous electrical and magneto-thermoelectric properties
We synthesized the magnetic Weyl semimetal candidate Co3Sn2S2 as a thin film using the co-sputtering technique. By adjusting the film composition using a sulfur-rich SnS1.5 target with Co metal chips attached, we obtained highly crystallized, single-phase Co3Sn2S2 films. The films showed a ferromagnetic transition around 180 K with perpendicular remanent magnetization. We observed the anomalous Hall effect with a tangent of Hall angle of 0.20 at 130 K, as previously reported for the bulk single
