Additionally, nanostructuring—altering the material's structure at the nanoscale—has emerged as a powerful method to engineer band gaps. Despite its potential, Band Gap Engineering faces challenges, ...

An insulator has a band structure in which occupied and empty bands are separated by an energy gap. The existence of an energy gap, however, does not guarantee that a material is a simple insulator.

This transformation completely eliminates all the two-coordinate acetylenic carbons from graphyne, yet it preserves the layered structure. The transformation also modifies the band gap of the ...
