Atomistic mechanisms for bilayer growth of graphene on metal substrates
Chen, Wei; Cui, Ping; Zhu, Wenguang; Kaxiras, Efthimios; Gao, Yanfei; Zhang, Zhenyu (American Physical Society, 2015) -
Dual role of Fe dopants in enhancing stability and charge transfer in ( Li 0.8 Fe 0.2 ) OHFeSe superconductors
Chen, Wei; Zeng, Changgan; Kaxiras, Efthimios; Zhang, Zhenyu (American Physical Society, 2016)The recently discovered (Li0.8Fe0.2)OHFeSe superconductor provides a new platform for exploiting the microscopic mechanisms of high-T-c superconductivity in FeSe-derived systems. Using density functional theory calculations, ... -
Enhancing the Hydrogen Activation Reactivity of Nonprecious Metal Substrates via Confined Catalysis Underneath Graphene
Zhou, Yinong; Chen, Wei; Cui, Ping; Zeng, Jiang; Lin, Zhuonan; Kaxiras, Efthimios; Zhang, Zhenyu (American Chemical Society, 2016) -
Hardware-Accelerated Adaptive EWA Volume Splatting
Chen, Wei; Ren, Liu; Zwicker, Matthias; Pfister, Hanspeter (Institute of Electrical and Electronics Engineers, 2004)We present a hardware-accelerated adaptive EWA (elliptical weighted average) volume splatting algorithm. EWA splatting combines a Gaussian reconstruction kernel with a low-pass image filter for high image quality without ... -
Noncovalent Bonding Controls Selectivity in Heterogeneous Catalysis: Coupling Reactions on Gold
Karakalos, Stavros; Xu, Yunfei; Cheenicode Kabeer, Fairoja; Chen, Wei; Rodríguez-Reyes, Juan Carlos F.; Tkatchenko, Alexandre; Kaxiras, Efthimios; Madix, Robert J.; Friend, Cynthia M. (American Chemical Society, 2016)Enhancing the selectivity of catalytic processes has potential for substantially increasing the sustainability of chemical production. Herein, we establish relationships between reaction selectivity and molecular structure ... -
Theory of Graphene Raman Scattering
Heller, Eric J.; Yang, Yuan; Kocia, Lucas; Chen, Wei; Fang, Shiang; Borunda, Mario; Kaxiras, Efthimios (American Chemical Society (ACS), 2016)Raman scattering plays a key role in unraveling the quantum dynamics of graphene, perhaps the most promising material of recent times. It is crucial to correctly interpret the meaning of the spectra. It is therefore very ... -
Tuning the Electronic and Chemical Properties of Monolayer MoS 2 Adsorbed on Transition Metal Substrates
Chen, Wei; Santos, Elton J. G.; Zhu, Wenguang; Kaxiras, Efthimios; Zhang, Zhenyu (American Chemical Society, 2013)
