Adsorbate-induced Restructuring of Pb mesas Grown on Vicinal Si(111) in the Quantum Regime (2009)

Khajetoorians, Alexander Ako, Zhu, Wenguang, Kim, Jisun, Qin, Shengyong, Eisele, Holger, Zhang, Zhenyu, ...

Using scanning tunneling microscopy and spectroscopy, we demonstrate that the adsorption of a minute amount of Cs on a Pb mesa grown in the quantum regime can induce dramatic morphological changes of...

Contrast behaviors in the adsorption, diffusion, nucleation, and growth of carbon adatoms on stepped metal surfaces (2009)

Chen, Hua, Zhu, Wenguang, Zhang, Zhenyu

To reveal the growth mechanism in the initial nucleation stage of graphene on metal surfaces, in this work we study the energetics and kinetics of carbon adatoms on three (stepped) metal surfaces:...

Optimization of Mn Doping in Group-IV-based Dilute Magnetic Semiconductors by Electronic Co-dopants (2009)

Chen, Hua, Zhu, Wenguang, Kaxiras, Efthimios, Zhang, Zhenyu

The percentage of substitutional doping of magnetic atoms (Mn) in group-IV-based dilute magnetic semiconductors (DMS) can be increased by co-doping with another conventional electronic dopant...
