Abstract
Description
도 1b는 본 발명의 실시예의 순환 전압전류법에서 산화 영역에서의 전하량의 증가와 환원 영역에서 전하량의 증가가 유사한 양임을 보여주는 그래프이다.
도 2a 내지 d는 40mA/cm2의 일정 전류 밀도를 인가하여 얻은 Zn 전해 박막의 현미경 이미지로서, 전해질 내에 첨가된 SnO 함량에 따른 Zn 전해박막의 형상 변화를 보여주는 결과이다.
도 3a는 SnO가 첨가된 경우 제조된 전해 도금층을 추가로 분석하기 위해, 동적 SIMS 분석을 사용하여, 3×10-3 M SnO 함유 전해질 내에서 제조된 전해 도금층에 대해 화학 깊이 분석법(chemical depth profile)을 수행한 결과이다.
도 3b는 X-선 회절분석 패턴을 보여주며, Sn이 정방정계 구조를 가짐과 함께 Zn의 전형적 6방정계 밀집 구조를 보여준다.
도 4는 실시예 7로 얻은 도금층의 현미경 이미지이다.
