First-principles investigation of organic photovoltaic materials C, C, [C]PCBM, and bis-[C]PCBM using a many-body -Lanczos approach
Xiaofeng Qian, Paolo Umari, Nicola Marzari
We present a first-principles investigation of the excited-state properties of electron acceptors in organic photovoltaics including C, C, [6,6]-phenyl-C-butyr…

Envelope function method for electrons in slowly-varying inhomogeneously deformed crystals
Wenbin Li, Xiaofeng Qian, Ju Li
We develop a new envelope-function formalism to describe electrons in slowly-varying inhomogeneously strained semiconductor crystals. A coordinate transformation is used to map a d…

Topological Crystalline Insulator Nanomembrane with Strain-Tunable Band Gap
Xiaofeng Qian, Liang Fu, Ju Li
The ability to fine-tune band gap and band inversion in topological materials is highly desirable for the development of novel functional devices. Here we propose that the electron…
