“…1(b)). We believe that the critical exponent value for the bandwidth of delocalized states, 0.54 0.01, κ = ± obtained by us in [39] for HgTe-based heterostructure with inverted band spectrum, as well as a number of results with κ = 0.5-0.75 for systems with large-scale impurity potentials (see Table 1) are driven by a situation schematically represented on Fig. 1 .…”

“…Значения κ при T > 2 K, определенные в настоящем исследовании, хорошо согласуются со значениями, получаемыми на системах с крупномасштабным случайным потенциалом [6,7,11,15,28,29,33,35,36,[40][41][42][43][44]. В частности, во множестве работ для наиболее изученной структуры GaAs/AlGaAs регулярно наблюдаются κ = 0.5−0.75.…”

“…Недавно была исследована температурная зависимость ширины области перехода между плато КЭХ в квантовых ямах HgTe с инвертированным зонным спектром [40]. Было обнаружено скейлинговое поведение с критическим индексом κ = 0.54 ± 0.01 на переходе 1 → 2 в широком интервале температур T = 2.9−30 K [40].…”

“…In our previous paper [10] we have studied the QHE plateau-plateau transition for a wide temperature range T = 2.9-50 K at HgCdTe/HgTe/HgCdTe system with the inverted band structure. In subsequent work [11] the first study of variable-range hopping conductivity at the QHE plateau regions in the HgTe/HgCdTe heterostructure has been done.…”
