2019 Spring Physics Colloquium
강연일자: 2019. 05. 21. 화. 오후 5시
장소: 아산이학관 433호
강연자: 이탁희 (서울대)
강연주제: Molecular-Scale Electronic Devices
In this talk, I will review our group research works on molecular-scale
electronic devices [1]. Specifically, I will focus on high-yield molecular
electronic junctions with device functionalities such as rectifying or
photoswitching molecular devices on rigid or flexible substrates [2]. And then,
I will give an overview of our research on polymer or perovskite-based memory
devices [3]. In particular, I will explain the orthogonal lithography which
enables microscale integration of organic memory cells in the cross-bar
architecture [3] and noise characteristics in relation with memory mechanism
[4]. If time allows, I will explain briefly our studies on interface and
surface control on two-dimensional transition metal dichalcogenide-based field
effect transistors with molecular treatments [5].
