Over the past 50 years, two-dimensional (2D) electronic systems have served as a key material platform for the study of intriguing quantum phenomena in engineered material systems. More recently, scientists have found that it is possible to fabricate atomically thin van der Waals (vdW) layered materials. In these atomically thin materials, quantum physics allows electrons to move effectively only in a 2D space. By stacking these 2D quantum materials, it is also possible to create vdW heterostructures with a wide range of interfacial electronic and optical properties. Novel 2D electronic systems realized in vdW atomic stacks have served as a platform for engineered quantum materials. In this talk, we will discuss several research efforts to realize emergent physical phenomena in stacked atomic thin film materials and possible applications based on these materials. I will focus our discussion on unusual quasiparticle pairing and emergent physical phenomena associated with many-body quantum systems enabled in vdW heterostructures.
About the speaker:
Prof. Kim studied physics at Seoul National University and earned his bachelor's degree in 1990, a master's degree in 1992, and a doctorate in applied physics at Harvard University in 1999 under the supervision of Charles Lieber. He worked at the University of California, Berkeley as a Miller Research Fellow until 2001, when he joined the faculty at Columbia University where much of his seminal work was carried out. He later moved to Harvard University in 2014 as a professor of Physics and Applied Physics. Kim received a National Science Foundation Early Career Development Award in 2004. In 2006, he was named as one of the "Scientific American 50", a list of individuals/organizations honored for their contributions to science and society during the preceding year. Kim has received the 2008 Ho-Am Prize in Science, the APS Buckley prize, and other awards.
