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…
Valley Depolarization in Monolayer Transition-Metal Dichalcogenides with Zone-Corner Acoustic Phonons
Tae-Young Jeong, Soungmin Bae, Seong-Yeon Lee +3
Although single-layer transition-metal dichalcogenides with novel valley functionalities are promising candidate to realize valleytronic devices, the essential understanding of val…
Spectroscopic studies of atomic defects and bandgap renormalization in semiconducting monolayer transition metal dichalcogenides
Tae Young Jeong, Hakseong Kim, Sang-Jun Choi +5
Assessing atomic defect states and their ramifications on the electronic properties of two dimensional van der Waals semiconducting transition metal dichalcogenides (SC TMDs) is th…
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…
Broken-Symmetry Quantum Hall States in Twisted Bilayer Graphene
Youngwook Kim, Jaesung Park, Intek Song +8
Twisted bilayer graphene offers a unique bilayer two-dimensional-electron system where the layer separation is only in sub-nanometer scale. Unlike Bernal-stacked bilayer, the layer…
Mechanism for puddle formation in graphene
Shaffique Adam, Suyong Jung, Nikolai N. Klimov +3
When graphene is close to charge neutrality, its energy landscape is highly inhomogeneous, forming a sea of electron-like and hole-like puddles, which determine the properties of g…
Microscopic Polarization in Bilayer Graphene
Gregory M. Rutter, Suyong Jung, Nikolai N. Klimov +3
Bilayer graphene has drawn significant attention due to the opening of a band gap in its low energy electronic spectrum, which offers a promising route to electronic applications.…
Evolution of Microscopic Localization in Graphene in a Magnetic Field from Scattering Resonances to Quantum Dots
Suyong Jung, Gregory M. Rutter, Nikolai N. Klimov +5
