Quasiparticle band alignment and stacking-independent exciton in MAZ (M = Mo, W, Ti; A= Si, Ge; Z = N, P, As)
Hongxia Zhong, Guangyong Zhang, Cheng Lu +1
Motivated by the recently synthesized two-dimensional semiconducting MoSiN, we systematically investigate the quasiparticle band alignment and exciton in monolayer MAZ$…
Radiative properties of quantum emitters in boron nitride from excited state calculations and Bayesian analysis
Shiyuan Gao, Hsiao-Yi Chen, Marco Bernardi
Point defects in hexagonal boron nitride (hBN) have attracted growing attention as bright single-photon emitters. However, understanding of their atomic structure and radiative pro…
Raman Response and Transport Properties of One-Dimensional van der Waals Tellurium Nanowires
Jing-Kai Qin, Pai-Ying Liao, Mengwei Si +15
Tellurium can form nanowires of helical atomic chains. Given their unique one-dimensional van der Waals structure, these nanowires are expected to show remarkably different physica…
Emerging Photoluminescence from the Dark-Exciton Phonon Replica in Monolayer WSe2
Zhipeng Li, Tianmeng Wang, Chenhao Jin +13
Tungsten-based monolayer transition metal dichalcogenides host a long-lived dark exciton, an electron-hole pair in a spin-triplet configuration. The long lifetime and unique spin p…
Edge-Insensitive Magnetism and Half Metallicity in Graphene Nanoribbons
Shiyuan Gao, Li Yang
Realizing magnetism in graphene/carbon nanostructures is a decade-long challenge. The magnetic edge state and half metallicity in zigzag graphene nanoribbons are particularly promi…
Interlayer coupling and gate-tunable excitons in transition metal dichalcogenide heterostructures
Shiyuan Gao, Li Yang, Catalin D. Spataru
Bilayer van der Waals (vdW) heterostructures such as MoS2/WS2 and MoSe2/WSe2 have attracted much attention recently, particularly because of their type II band alignments and the f…
Renormalization of quasiparticle band gap in doped two-dimensional materials from many-body calculations
Shiyuan Gao, Li Yang
Doped free carriers can substantially renormalize electronic self-energy and quasiparticle band gaps of two-dimensional (2D) materials. However, it is still challenging to quantita…
Ligand-field helical luminescence in a 2D ferromagnetic insulator
Kyle L. Seyler, Ding Zhong, Dahlia R. Klein +11
Bulk chromium triiodide (CrI) has long been known as a layered van der Waals ferromagnet. However, its monolayer form was only recently isolated and confirmed to be a truly two…
Quasiparticle Band Gaps, Excitonic Effects, and Anisotropic Optical Properties of Monolayer Distorted 1-T Diamond-chain Structures
Hong-Xia Zhong, Shiyuan Gao, Jun-Jie Shi +1
We report many-body perturbation theory calculations of excited-state properties of distorted 1-T diamond-chain monolayer rhenium disulfide (ReS2) and diselenide (ReSe2). Electroni…
