摘要:2D layered materials, including graphene, transition metal dichalcogenides (TMDs) allow the scaling down to atomically thin thicknesses and possess unique physical properties under dimensionality confinement. Chemical vapor deposition (CVD) process is the most popular approach for all kinds of 2D materials due to its high yield and quality. However, the transfer procedure has become one of the major limitations of the overall performance. In my talk, I will present several approaches, including ultra-fast microwave heating, plasma selective reaction, controlled segregation process by laser irradiation and metal vaper-assisted growth processes developed in my lab these years to directly grow graphene with controllable thicknesses on arbitrary substrates without any extra transfer process. Also, an inductively coupled plasma (ICP) was used to synthesize TMDs through a plasma-assisted selenization process of metal oxide (MOx) at a low temperature, as low as 250 °C. The applications including (1) water splitting, (2) gas sensors and (3) batteries will be reported.

简介:Prof. Yu-Lun Chueh received his Ph.D degree from the department of materials science and engineering, National Tsing Hua University, Taiwan in 2006 and worked as postdoctoral in electrical engineering and computer science, UC Berkeley from 2007-2009. He joined the department of materials science and engineering, National Tsing Hua University in 2009. Currently, He is a professor in the department of materials science and engineering, National Tsing Hua University, Taiwan. He has published 252 peer-reviewed papers and 25 patents with total citations >12000 and h-index of 52. The research activities of his lab are highly interdisciplinary and are committed to exploring new unpredicted levels of functional materials to enable new schemes on manipulating and processing of engineering nanomaterials in nanoelectronics and energy harvesting applications.
