Hexagonal Silicon Realized

Nano Letters, 2015
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.

Triplets and Hexagons

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.

Hexagonal Distributions on Hexagonal Lattice

2013
An 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.
