Network Covalent Solids

Network Covalent Solids

Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

Area of Science:

Materials Science
Condensed Matter Physics
Surface Science

Background:

Graphene's discovery initiated the 2D materials era, leading to diverse hydrogenated forms with tunable properties.
Previous patterned hydrogenated graphene was limited to micron scales using lithography.

Purpose of the Study:

To report the millimeter-scale synthesis of intrinsically honeycomb-patterned hydrogenated graphene (HPHG).
To elucidate the growth mechanism and explore the properties of HPHG.

Main Methods:

Epitaxial growth of graphene on Ru(0001) followed by hydrogenation.
Scanning tunneling microscopy (STM) for surface observation.
Density-functional-theory (DFT) calculations for theoretical analysis.

Main Results:

An atomic-hydrogen layer intercalates between graphene and Ru(0001), forming a hydrogen honeycomb template.
Graphene is hydrogenated only over the template, creating HPHG, a patterned graphane.
DFT calculations reveal spin-polarized edge states in the unhydrogenated graphene regions.

Conclusions:

A novel growth mechanism enables the intrinsic patterning of hydrogenated graphene at the millimeter scale.
HPHG offers a new class of patterned 2D materials with potential applications in electronics and spintronics.
