Silicon, arguably the most important technological semiconductor, is predicted to exhibit a range of new and interesting properties when grown in the hexagonal crystal structure. To obtain pure hexagonal silicon is a great challenge because it naturally crystallizes in the cubic structure.

Rook domination on hexagonal hexagon boards
2022Summary: Chess-like game boards \(B_n\) are considered, which are hexagonal parts of the Euclidean tessellation of the plane by regular hexagons. For chess-like rooks on \(B_n\) the domination number \(\gamma(n)\) is determined.

Hexagonal Distributions on Hexagonal Lattice
2013An infinite hexagonal lattice is introduced as a two-dimensional discretized uniform space for economic agglomeration. This chapter focuses on an analysis of geometrical characteristics of the lattice, as a vital prerequisite for the group-theoretic bifurcation analysis of this lattice that will be conducted in Chaps. 6–9.

Hexagonal molecular “palladawheel”
Chemical Communications, 2013A hexagonal molecular "palladawheel" consisting of six N,N'-diphenyl-2,6-pyridinedicarboxamide-Pd(II) pincer complexes held together via six Pd∙∙∙O=CAmide bonds was efficiently synthesized and crystallographically characterized. The hexameric ring possesses C3 (pseudo-S6) symmetry with up-down alternating phenyl substituents acting as interior "spokes"

Hexagonal Mesoporous Germanium
Science, 2006The blending of mesoporosity with the properties of semiconductors promises new types of multifunctional nanomaterials. It would be particularly interesting to combine the shape selectivity of a mesoporous oxide with the electronic and photonic characteristics of a useful semiconductor.

Graphs and Combinatorics, 1993
Two classes of cubic graphs are introduced. Their construction is based on the geometry of the projective line. For instance, \(T(p)\), where \(p\) is an odd prime, has as vertices the 3-subsets of \(\text{PG} (1,p)\), where \(\{a,b,c\}\) and \(\{a,b,d\}\) are adjacent when the pairs \(\{a,b\}\) and \(\{c,d\}\) harmonically separate each other.

In this chapter, we give the classification of hexagonal systems as formulated in Theorem 17.6. Our goal is to show that the list of hexagonal systems described in (15.14) and summarized in Figure 2 on page 148 is complete.
