Phonon-Assisted Radiative Lifetimes and Exciton Dynamics from First Principles
Chunhao Guo, Gabriele Riva, Jacopo Simoni +2
Exciton-phonon interactions play a fundamental role in phonon-assisted radiative recombination and exciton dynamics in solids. In this work, we present a first-principles framework…
Effect of Environmental Screening and Strain on Optoelectronic Properties of Two-Dimensional Quantum Defects
Shimin Zhang, Kejun Li, Chunhao Guo +1
Point defects in hexagonal boron nitride (hBN) are promising candidates as single-photon emitters (SPEs) in nanophotonics and quantum information applications. The precise control…
Substrate Effect on Excitonic Shift and Radiative Lifetime of Two-Dimensional Materials
Chunhao Guo, Junqing Xu, Yuan Ping
Substrates have strong effects on optoelectronic properties of two-dimensional (2D) materials, which have emerged as promising platforms for exotic physical phenomena and outstandi…
Substrate screening approach for quasiparticle energies of two-dimensional interfaces with lattice mismatch
Chunhao Guo, Junqing Xu, Dario Rocca +1
Two-dimensional (2D) materials are outstanding platforms for exotic physics and emerging applications by forming interfaces. In order to efficiently take into account the substrate…
