Recently, the research scientist Shern-Long Lee from IAS was Invited to Publish a Ppaper by the Royal Society of Chemistry (RSC).Chemical Communications is the most important periodical of RSC and JCR. Researcher scientist Shern-Long Lee Shenglong published contributed the latest research results on the magazine under the title of "Superstructure manipulation and electronic measurement of monolayers cured by a discotic liquid crystalline with intrinsic dipole moment using STM/STS". This research is proposed by Dr. Lee and Professor Chen, Chun-hsien from Taiwan University and Professor Wang Zhiwei from Sun Yat-Sen University. The Institute for Advanced Study is the first communication author unit, and the experiment was completed by Zheng Kunyi, a student of NTU Chemistry Department of National Taiwan University.
Discotic liquid crystallines (DLCs) are common in today's technology, including modern screen displays. Liquid crystal materials can be spontaneously integrated into 3D columnar structures to facilitate the transfer of electrons. Today, many documents claim that the efficiency of electronic components is closely related to the few layers of materials that contact the electrode faces, so the study of the photovoltaics of the thin-layer assembled materials is extremely important. In this paper, scanning tunneling microscopy (STM) is combined with scanning tunneling spectroscopy (STS) measurement technique, which is used to investigate the band gap of single-layer liquid crystal molecular materials with molecular self-assembly structure. More important in this paper is the molecular assembly structure can be controlled by the direction of the STM electric field due to the permanent dipole of the molecules used in this study. This study is based on real-time image monitoring of reversible supramolecular assembly structure and its semiconductor molecular energy band changes, and a novel liquid crystal material assembly structure control and real-time electrical measurement technology platform is developed and proposed.
“Scanning probe frontiers in molecular 2D-architecture” themed issue.
