Researchers Have Identified High Hexagonal Diamond Mobility
A new study confirms hexagonal diamond carrier mobilities exceed those observed in standard cubic diamond.
Updated on Sept. 19, 2026 in Materials Science
Scientists have determined that hexagonal diamond possesses exceptional carrier mobilities. This breakthrough provides new insights into the material properties of this specific diamond structure.
Why it matters
Understanding these material properties is crucial for future semiconductor applications. Superior carrier mobility allows for faster and more efficient electronic devices.
Hexagonal diamond exhibits electron mobility reaching 28,473 cmVs along the ∥c direction and 12,339 cmVs along the ⊥c direction. Hole mobility was measured at 6024 cmVs and 6000 cmVs respectively.
The details
The enhanced performance is driven by symmetry-enforced selection rules that suppress scattering for transverse acoustic phonons. Additionally, electron-phonon decoupling occurs due to a spatial mismatch between wavefunctions and scattering potentials.
