Abstract
We demonstrate the existence of a family of stable boron fullerenes containing atoms that is related to the family of carbon icosahedral fullerene series and is compatible with the recently proposed stable boron sheets composed of triangular and hexagonal motifs. All electron density-functional calculations on the , , , and confirm their stability and show that the quantum size effects open up electronic band gaps in the boron fullerenes at . Boron fullerenes below have valence electronic structure identical to their corresponding carbon cousins from family.
