Quasiparticle Levels at Large Interface Systems from Many-body Perturbation Theory: the XAF-GW method
Fengyuan Xuan, Yifeng Chen, Su Ying Quek
We present a fully ab initio approach based on many-body perturbation theory in the GW approximation, to compute the quasiparticle levels of large interface systems without signifi…

Point Defects and Localized Excitons in 2D WSe2
Yu Jie Zheng, Yifeng Chen, Yu Li Huang +8
Identifying the point defects in 2D materials is important for many applications. Recent studies have proposed that W vacancies are the predominant point defect in 2D WSe2, in cont…

Energy Level Alignment at Hybridized Organic-metal Interfaces: the Role of Many-electron Effects
Yifeng Chen, Isaac Tamblyn, Su Ying Quek
Hybridized molecule/metal interfaces are ubiquitous in molecular and organic devices. The energy level alignment (ELA) of frontier molecular levels relative to the metal Fermi leve…
