Using the minima hopping global geometry optimization method on the density functional potential energy surface we show that the energy landscape of boron clusters is glasslike. Larger boron clusters have many structures which are lower in energy than the cages. This is in contrast to carbon and boron nitride systems which can be clearly identified as structure seekers. The differences in the potential energy landscape explain why carbon and boron nitride systems are found in nature whereas…

Boron aggregation in the ground states of boron-carbon fullerenes
We present unexpected structural motifs for boron-carbon nanocages of the stoichiometries B12C48 and B12C50, based on first-principles calculations. These configurations are distinct from those
Stabilization of boron clusters with classical fullerene structures by combined doping effect: a quantum chemical study
A combined approach (endohedral doping and exohedral environment) to stabilization of boron clusters with classical fullerene structures has been studied. The boron clusters with classical fullerene
Selecting boron fullerenes by cage-doping mechanisms.
A guiding principle for the stability of boron fullerenes is formulated, which takes the form of an isolated filled pentagon rule (IFPR), and it is shown that the interplay of the IFPR and the seed-induced doping breaks polymorphism and its related problems.
Thermodynamically stable polymorphs of nitrogen-rich carbon nitrides: a C3N5 study.
It is found that stacked, planar, graphite-like structures are energetically the most stable carbon nitride polymorphs for various nitrogen contents but this does not apply for nitrogen-rich materials owing to the high abundance of N-N bonds.
Low-dimensional boron: searching for Dirac materials
Abstract Two-dimensional (2D) boron, as an analog of graphene, can serve as a building block for fullerenes, nanotubes, and nanoribbons. Understanding its structure and stability is a prerequisite
Fullerene-like boron clusters stabilized by an endohedrally doped iron atom: B(n)Fe with n = 14, 16, 18 and 20.
Stabilized fullerene and tubular forms can be produced in boron clusters Bn in small sizes from n∼ 14 to 20 upon doping by transition metal atoms and suggest the use of dopants to induce different growth paths leading to larger cages, fullerenes and tubes of borons.
Observation of an all-boron fullerene.
The observation of an all-boron fullerene-like cage cluster at B40(-) with an extremely low electron-binding energy is reported, by photoelectron spectroscopy, and theoretical calculations show that this arises from a cage structure with a large energy gap, but that a quasi-planar isomer of B40 (-) with two adjacent hexagonal holes is slightly more stable than the fullerenes structure.
A new hole density as a stability measure for boron fullerenes.
A new hole density definition is proposed such that each member of a fullerene group has a different hole density which depends on the capping process, and a new stability measure relating the cage geometry characterized by the hole density to the relative energy is proposed.

I and i
There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.
