Weak Coloring Numbers of Intersection Graphs

Zdeněk Dvořák, Jakub Pekárek, Torsten Ueckerdt +1

Weak and strong coloring numbers are generalizations of the degeneracy of a graph, where for each natural number , we seek a vertex ordering such every vertex can (weakly respec…

Space charge limited photocurrents and transient currents in CdZnTe radiation detectors

Katarina Ridzonova, Eduard Belas, Roman Grill +2

We combined steady-state photoconductivity and laser-induced transient current measurements under above-band-gap illumination to study the space charge formation in CdZnTe. Analyti…

Coloring near-quadrangulations of the cylinder and the torus

Zdeněk Dvořák, Jakub Pekárek

Let G be a simple connected plane graph and let C_1 and C_2 be cycles in G bounding distinct faces f_1 and f_2. For a positive integer l, let r(l) denote the number of integers n s…

Deep Levels and Mixed Conductivity in Organometallic Halide Perovskites

Artem Musiienko, Pavel Moravec, Roman Grill +10

Understanding the type, formation energy and capture cross section of defects is one of the challenges in the field of organometallic halide perovskite (OMHP) devices. Currently, s…

Influence of deep levels on the electrical transport properties of CdZnTeSe detectors

M Rejhon, J Franc, V Dědič +4

We investigated the influence of deep levels on the electrical transport properties of CdZnTeSe radiation detectors by comparing experimental data with numerical simulations based…

Irreducible 4-critical triangle-free toroidal graphs

Zdeněk Dvořák, Jakub Pekárek

The theory of Dvorak, Kral, and Thomas (2015) shows that a 4-critical triangle-free graph embedded in the torus has only a bounded number of faces of length greater than 4 and that…
