“…[79][80][81][82][83]109,110 They also display chemical bonding between ionic and covalent character, while also showing semimetallic behavior under pressure 111 or with temperature. 112 Therefore, simple attempts using either reverse Monte Carlo (RMC) simulations 102,[113][114][115] or classical molecular dynamics [116][117][118][119][120] (including the computation of the vibrational spectra 121 ) have failed in reproducing the details of the chemical bonding of GeSe 2 glasses, most of these computational efforts having been accomplished at a time when there was only indirect evidence of homopolar Ge-Ge and Se-Se bonds, 103,104 i.e., before the publication of the full partial structure factor analysis revealing in a neat way these bonding types. 109,110 More recent contributions using either three-body force fields 122,123 or polarizable ion models 124,125 still do not reproduce accurately the structure of GeSe 2 .…”

“…Количество потенциально разрывающихся связей в решетке алмаза зависит от величины вводимой энергии и от величины ее локальных флуктуаций. Поэтому степень деструкции может колебаться от возникновения дефектов решетки в виде отдельных разорванных связей до полного разделения целого кристалла на отдельные фрагменты [30].…”

“…Nucleation of graphite inside a diamond by phase change is a spontaneous high-temperature process that starts at impurities and structure defects. The physical process is much faster than the chemical one (Andreev, 1999), and the rates of both are directly proportional to temperature and, possibly, inversely proportional to total pressure (Qian et al, 2004 ;Sonin et al, 2013).…”
