본문내용
Bandgap opening in graphene induced by patterned hydrogen adsorption
♦ Sample Preparation (Hydrogen atom on Graphene)
Epitaxial graphene on Ir(111) crystal
→ atomic hydrogen was deposited onto the graphene layer at room temperature by means of 2100 K hot H-atom beam with a flux of ~1013 – 1014 atoms/cm2s
♦ STM images of hydrogen adsorbate structures following and preserving the Moire pattern of graphene on Ir(111)
a) Moire pattern of clean graphene on Ir(111)
b) graphene exposed to atomic hydrogen for very low dose, 15 s
c) 30 s
d) 50 s
e) 50 s. illustrating that hydrogen adsorbate structures preserve the Moire periodicity.
