Recent Applications of Voronoi Tesselation and Analysis of Their Size Distributions with the Generalized Wigner Surmise

ORAL

Abstract

While Voronoi tessellation has long been applied in spatial studies, analysis of their cell-size distribution using the single-adjustable-parameter generalized Wigner surmise, Pβ(s) = asβexp(-bs2, has only been done in the last decade. Here we discuss some intriguing examples: Mitko et al. (2019) consider the evolution of morphology during growth of island films of low-e dielectric films via vapor deposition polymerization. Löbl et al. (2019) probe infilling Al-droplet-etched nanoholes in an AlGaAs surface. In both cases, estimates of the critical nucleus size were extracted from the value of the exponenet β determined from a fit to Pβ(s). We discuss the results and their implications. In other tantalizing examples, the Voronoi cell-size was not [yet] analyzed using Pβ(s). Brookes (2017) uses Voronoi analysis of cells on the outer layer of eye-banked corneas to assess their viability before transplanting. Konishi et al. (2017) studied the growth-rate dependence of the spatial distribution of self-assembled 2D quantum dots on InAs-GaAs. They also consider the influence of modest array size.
