Carrier Capture at Defects from Finite-Temperature Lattice Dynamics
Menglin Huang, Shanshan Wang, Shiyou Chen
Defect-assisted carrier capture is commonly described within nonradiative multiphonon (NMP) theory using normal modes of the equilibrium defect structure. This description becomes…
Nonradiative Multiphonon Model of Deep-Level Transient Spectroscopy: Beyond Henry-Lang Model
Menglin Huang, Shanshan Wang, Junjie Zhou +2
Deep-level transient spectroscopy (DLTS) is a key experimental method for defect characterization, yet its analysis remains controversial, and the two widely used models developed…
Electroluminescence of NV Color Centers in Diamond p-i-n Diodes mediated by Charge-state Dynamics
Ruirong Bai, Menglin Huang, Shanshan Wang +2
As the electroluminescence (EL) of NV color centers in diamond has been realized in p-i-n diodes,the underlying mechanism remains a puzzle for longer than a decade. In this study,u…
Carrier Emission and Capture Competition mediated A(n)BC Recombination Model in Semiconductors with Multi-Level Defects
Shanshan Wang, Menglin Huang, Su-Huai Wei +2
The ABC model has been widely used to describe the carrier recombination rate, in which the rate of non-radiative recombination assisted by deep-level defects is assumed to depend…
Defect Phonon Renormalization during Nonradiative Multiphonon Transitions in Semiconductors
Junjie Zhou, Shanshan Wang, Menglin Huang +2
As a typical nonradiative multiphonon transition in semiconductors, carrier capture at defects is critical to the performance of semiconductor devices. Its transition rate is usual…
Metastability and anharmonicity enhance defect-assisted nonradiative recombination in low-symmetry semiconductors
Menglin Huang, Shanshan Wang, Shiyou Chen
Strong nonradiative recombination has been observed in quasi-one-dimensional antimony selenide, which runs counter to the simple intuition that claims high defect tolerance exists…
Defect Regulation by Palladium Incorporation towards Grain Boundaries of Kesterite solar cells
Jinlin Wang, Jiangjian Shi, Kang Yin +10
Kesterite Cu2ZnSn(S, Se)4 (CZTSSe) solar cell has emerged as one of the most promising candidates for thin-film photovoltaics. However, severe charge losses occurring at the grain…
Effective Lifetime of Non-Equilibrium Carriers in Semiconductors from Non-Adiabatic Molecular Dynamics Simulations
Shanshan Wang, Menglin Huang, Yu-Ning Wu +6
The lifetime of non-equilibrium electrons and holes in semiconductors is crucial for solar cell and optoelectronic applications. Non-adiabatic molecular dynamics (NAMD) simulations…
DASP: Defect and Dopant ab-initio Simulation Package
Menglin Huang, Zhengneng Zheng, Zhenxing Dai +5
In order to perform automated calculations of defect and dopant properties in semiconductors and insulators, we developed a software package, Defect and Dopant ab-initio Simulation…
