Abstract

From the perspective of materials science, emerging materials for next-generation microelectronics are on the horizon as silicon-based devices reach the fundamental limit. Although a myriad of emerging materials are on the table of basic research and development, there are common aspects which are required to fulfill for microelectronic devices. Atomically thin two-dimensional (2D) materials are the material class considered as promising building blocks. However, adoption of 2D materials should solve several issues. The issues would be resolved by integrated efforts of growth, characterization, and post-processing. In addition to the 2D materials, other materials including conventional semiconductors in new forms are also investigated. Semiconductor nanomembranes and nanowires show interesting properties and would be compatible to existing manufacturing infrastructure. In the presentation, I’ll discuss ion beam irradiation of 2D materials and novel observation in silicon-germanium nanowires for next-generation electronic device applications.

Biography

Jinkyoung Yoo is the co-leader of Quantum Materials Systems thrust of The Center for Integrated Nanotechnologies (CINT), a National Nanoscience Research Center supported by U.S. Department of Energy (DOE), in Los Alamos National Laboratory. He is also a member of the Quantum Science Center, one of five DOE Quantum Information Science Center. He is serving as a panel of the technology council of heterogeneous integration for Semiconductor Research Corporation. He is a principal editor of Journal of Materials Research, edited by Materials Research Society and published by Springer-Nature. He received his Ph. D. (Materials Science) from the Pohang University of Science and Technology (POSTECH) in South Korea. He worked at CINT as a post-doctoral researcher from 2010 to 2013. He then joined CINT as a technical staff member in 2013. His research encompasses synthesis of semiconductor nanowire heterostructures, 2D/3D heterostructures, electrical/optical characterizations, and device fabrication to integrate fundamental understandings of nanoscience into applicable devices.
