Image-force effects on energy level alignment at electron transport material/cathode interfaces
TL;DR: In this paper, the authors systematically explore the commonly used ETM bathophenanthroline (BPhen) deposited on a series of conducting substrates, and show that the energy at the BPhen interface follows the typical integer charge transfer (ICT) model with an extra displacement of the vacuum level by up to −1.4 eV.
Journal ArticleDOI

Qinye Bao,Qinye Bao,Xianjie Liu,Slawomir Braun,Yan-Qing Li,Jian-Xin Tang,Chun-Gang Duan,Mats Fahlman +7 more
TL;DR: In this paper, the donor/acceptor bulk heterojunction (BHJ) blends of poly[2,3-bis-(3-octyloxyphenyl) quinoxaline-5, 8-dilyl-alt-thiophene-2, 5-diyl] have been investigated using ultraviolet photoemission spectroscopy (UPS) in combination with the integer charge transfer model.
Journal ArticleDOI
Experimental and Theoretical Investigation into the Polaron Structure of K-Doped Polyfluorene Films
TL;DR: In this article, the evolution of the electronic structure and optical transition upon n-doping of poly(9,9-dioctylfluorene) (PFO) films is elucidated with photoelectron spectroscopy, optical absorption, density fu...
Journal ArticleDOI
An organic memory phototransistor based on oxygen-assisted persistent photoconductivity
TL;DR: In this article, the PPC behavior is associated with photogenerated electrons trapped in oxygen atom-induced the reduced Lowest Unoccupied Molecular Orbitals or oxygen molecule-induced new trap state within energy bandgap of organic semiconductor.
Journal ArticleDOI
Energy level alignment at the interface of cadmium sulphide single crystal and phthalocyanines: The role of the crystal surface states
TL;DR: In this paper, the energy levels of (0001) and (000 (1) over bar) surfaces of bare CdS crystal terminated with Cd and S atoms, respectively, as well as energy level of (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 20, 21, 22, 23, 24, 28, 29, 30, 31, 34, 34
