Outline of Research at the Start

グラフェンを構成する炭素と同じ14族元素でハニカム構造を形成すれば、スピン軌道相互作用の効果によりエネルギーギャップが形成され、さらには、トポロジカル絶縁体となることが理論的に予想されている。14族元素で一番重い鉛原子からなる二次元ハニカムシート(以後、プランベンと呼ぶ)の創製は、至高の目標とされてきた。本研究では、プランベンを固体表面上で創製し、その幾何構造や電子状態を実験的に明らかにすることを目的とする。プランベンがスピントロニクスのための新素材として、新たな価値が創造され、バルクとは異なる物性を有する二次元物質がさらに注目を浴び、未知なる二次元物質の創製研究へとつながることが期待される。

Outline of Final Research Achievements

We investigated the electronic state at the edge of plumbene and the presence of superconductivity. The sample was prepared using a Pd(111) single crystal for a honeycomb nanosheet (plumbene) made of lead by segregation growth. Observations and measurements were conducted using a low-temperature scanning tunneling microscope and spectroscopy across the step edges. A characteristic peak was observed near the edge. As the measurement position moved away from the edge, the peak decreased in size, concluding that this peak represents an edge-specific electronic state. To clarify the presence of superconductivity, we narrowed the range of the energy measured and performed STS (Scanning Tunneling Spectroscopy) spectrum measurements. The possibility of a superconducting gap beginning to form was suggested.

Academic Significance and Societal Importance of the Research Achievements

本研究では、プランベンのエッジが特異な電子構造を有することや超伝導の可能性が示唆された。プランベンが次世代エレクトロニクスの新素材として、新たな価値が創造され、バルクとは異なる物性を有する二次元物質がさらに注目を浴び、未知なる二次元物質の創製研究へとつながることが期待される。
