The present invention relates to a layered FeAs, a manufacturing method thereof and a FeAs nanosheet exfoliated therefrom and, more specifically, to a layered FeAs having a two-dimensional crystalline structure unlike traditional bulk FeAs, having excellent exfoliation properties, being easily exfoliated into a nanosheet form and having superconductivity. 본 발명은 층상형 FeAs, 이의 제조 방법 및 이로부터 박리된 FeAs 나노시트에 관한 것이며, 더욱 상세하게는 종래의 벌크형 FeAs와 달리 2차원 결정 구조를 갖고, 박리성이 우수하여 나노시트의 형태로 박리하기 용이하며, 초전도 특성을 갖는 층상형 FeAs에 관한 것이다.
