A versatile fabrication method for cluster superlattices
Alpha T. N'Diaye, Timm Gerber, Carsten Busse +3
On the graphene moire on Ir(111) a variety of highly perfect cluster superlattices can be grown as shown is for Ir, Pt, W, and Re. Even materials that do not form cluster superlatt…
Selecting a single orientation for millimeter sized graphene sheets
R. van Gastel, A. T. N'Diaye, D. Wall +7
We have used Low Energy Electron Microscopy (LEEM) and Photo Emission Electron Microscopy (PEEM) to study and improve the quality of graphene films grown on Ir(111) using chemical…
In situ observation of stress relaxation in epitaxial graphene
Alpha T. N'Diaye, Raoul van Gastel, Antonio J. Martinez-Galera +9
Upon cooling, branched line defects develop in epitaxial graphene grown at high temperature on Pt(111) and Ir(111). Using atomically resolved scanning tunneling microscopy we demon…
