Quantitative determination of interlayer electronic coupling at various critical points in bilayer MoS2
Wei-Ting Hsu, Jiamin Quan, Chi-Ruei Pan +7
Tailoring interlayer coupling has emerged as a powerful tool to tune the electronic structure of van der Waals (vdW) bilayers. One example is the usage of the moire pattern to crea…
Band gap renormalization and work function tuning in MoSe2/hBN/Ru(0001) heterostructures
Qiang Zhang, Yuxuan Chen, Chendong Zhang +4
Here we report the successful growth of MoSe2 on single layer hexagonal boron nitride (hBN) on Ru(0001) substrate by using molecular beam epitaxy. We investigated the electronic st…
Asymptotic Correction Schemes for Semilocal Exchange-Correlation Functionals
Chi-Ruei Pan, Po-Tung Fang, Jeng-Da Chai
Aiming to remedy the incorrect asymptotic behavior of conventional semilocal exchange-correlation (XC) density functionals for finite systems, we propose an asymptotic correction s…
Critical role of parallel momentum in quantum well state couplings in multi-stacked nanofilms: an angle resolved photoemission study
Woojoo Lee, Chi-Ruei Pan, Hyoungdo Nam +2
We use angle resolved photoemission spectroscopy (ARPES) to investigate the coupling of electron quantum well states (QWS) in epitaxial thin Pb and Ag films. More specifically, we…
Creating a Nanoscale Lateral Heterojunction in a Semiconductor Monolayer with a Large Built-in Potential
Madisen Holbrook, Yuxuan Chen, Hyunsue Kim +6
The ability to engineer atomically thin nanoscale lateral heterojunctions (HJs) is critical to lay the foundation for future two-dimensional (2D) device technology. However, the tr…
Epitaxial Growth of Two-dimensional Insulator Monolayer Honeycomb BeO
Hui Zhang, Madisen Holbrook, Fei Cheng +7
The emergence of two-dimensional (2D) materials launched a fascinating frontier of flatland electronics. Most crystalline atomic layer materials are based on layered van der Waals…
