Negative curvature energy in MgBx nanotubes published

July 18, 2016

Magnesium doped boron nanotubes can show a very unusual and unique property of having negative curvature energy: a small diameter nanotube can have lower energy per atom than a large diameter nanotube or flat sheet.  The paper shows the generality of this fact and also the underlying reasons for this behavior.  Published in Phyiscal Review B DOI 10.1103/PhysRevB.94.035425
