as a 2 eV Single-Photon Emitter Candidate in Hexagonal Boron Nitride
Kejun Li, Tyler Smart, Yuan Ping
The generation of single-photon emitters in hexagonal boron nitride around 2 eV emission is experimentally well-recognized; however the atomic nature of these emitters is unknown.…
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…
Intersystem Crossing and Exciton-Defect Coupling of Spin Defects in Hexagonal Boron Nitride
Tyler J. Smart, Kejun Li, Junqing Xu +1
Despite the recognition of two-dimensional (2D) systems as emerging and scalable host materials of single photon emitters or spin qubits, uncontrolled and undetermined chemical nat…
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…
Spin-phonon relaxation from a universal \emph{ab initio} density-matrix approach
Junqing Xu, Adela Habib, Sushant Kumar +3
Designing new quantum materials with long-lived electron spin states urgently requires a general theoretical formalism and computational technique to reliably predict intrinsic spi…
Optical Absorption Induced by Small Polaron Formation in Transition Metal Oxides -- The Case of CoO
Tyler J. Smart, Tuan Anh Pham, Yuan Ping +1
Small polarons (SPs) are known to exist in most important transition metal oxides (TMOs); however, the nature of small polaron formation remains enigmatic, and a fundamental unders…
