초록

이 논문에서는 기존의 초전도 현상을 바라보는 물리학자들의 생각의 흐름과 한계들을 살펴보고, 통계 열역학적 액체론의 관점에서 제시한 이론적 배경을 통해 상온 상압 초전도체가 개발될 수 있음을 약술하였다. 이것이 가능 할 방안은, 전자들이 돌아다닐 수 있는 상태수가 현저히 제한되는 1-Dimension에 가까운 전자 상태이어야 한다는 것과 그 상태에 있는 전자들이 액체적 특성이 나타날 수 있을 정도로 전자-전자 상호작용이 빈번한 상태이어야 한다는 것이다. 이러한 실행 예로서 우연한 기회에 실마리를 얻어 수많은 실험으로 구조를 밝혀낸 LK-99(본 연구에서 개발한 상온 상압 초전도체의 이름)의 개발 자료를 보고하며, 이에 세계 최초로 상압에서 임계온도가 97°C를 능가하는 초전도 물질의 특성과 발견에 대한 이론적, 실험적 근거를 요약하였다.

Abstract

This paper examines the way of thinking and limitations of physicists regarding the phenomenon of superconductivity and outlines how room-temperature and ambient-pressure superconductors can be developed through the statistical thermodynamic background of the liquid state theory. In hypothesis, the number of electron states should be limited by confining them to a state close to one-Dimension. Simultaneously, the electron-electron interactions should be frequent enough for the electrons to have liquid-like properties. As an example of implementing the hypothesis, our team reports the development of room-temperature and ambient-pressure superconductivity of a material named LK-99 (superconducting compound name developed in the research), whose structure was revealed through numerous experiments with a clue found by chance. Moreover, we summarize the theoretical and experimental basis for the characteristics and discovery of the world’s first superconducting material surpassing the critical temperature of 97°C at atmospheric pressure.
