Direct probing of phonon mode specific electron-phonon scatterings in two-dimensional semiconductor transition metal dichalcogenides: Symmetry and Berry phase
Duk Hyun Lee, Sang-Jun Choi, Hakseong Kim +2
Electron-phonon scatterings in solid-state systems are pivotal processes in determining many key physical quantities such as charge carrier mobilities and thermal conductivities. H…
A photonic platform hosting telecom photon emitters in silicon
Michael Hollenbach, Nagesh S. Jagtap, Ciarán Fowley +12
Silicon, a ubiquitous material in modern computing, is an emerging platform for realizing a source of indistinguishable single-photons on demand. The integration of recently discov…

Accurate Gap Determination in Monolayer and Bilayer Graphene/h-BN Moire Superlattices
Hakseong Kim, Nicolas Leconte, Bheema L. Chittari +5
High mobility single and few-layer graphene sheets are in many ways attractive as nanoelectronic circuit hosts but lack energy gaps, which are essential to the operation of field-e…
Bright visible light emission from graphene
Young Duck Kim, Hakseong Kim, Yujin Cho +18
Graphene and related two-dimensional materials are promising candidates for atomically thin, flexible, and transparent optoelectronics. In particular, the strong light-matter inter…
