○ 일시 : 2006년 10월 13일(금) 15:00-
○ 장소 : 자연과학관 A동 31214 첨단강의실
○ 연사 : 서 순 애 박사(삼성종합기술원)
○ 주제 : The Resistance switching mechanism of polycrystalline NiO thin film.
○ 초록 : Bi-stable conductive memory switching devices based on transition metal oxides (TMO) are
now emerging as a candidate for next generation non-volatile memories due to their superior
scalability, process compatibility and low voltage operation. Despite of remarkable development of the
memory devices of TMO, microscopic origin is still veiled. Bistable memory switching mechanism in
NiO thin films is investigated through several different experimental approach. Local filament formation
and rupture are strongly correlated with distribution of repetitive switching cycle. Our results validate
the feasibility of high density integration by controlling the complete confinement and number density of
filaments.
