Изучены возможные механизмы локализации носителей в неоднородных дырочно-легированных купратах и металл-диэлектрик переходы (МДП) в них. Показано, что диэлектрическое состояние легированных купратов отличается от состояния моттовского диэлектрика нелегиро- ванных купратов, характеризующихся щелью переноса заряда. Неоднородности, обусловленные легирующими примесями и носителями, способствуют разделению и упорядочению зарядов в виде трехмерных (3D), насыщенных и обедненных носителями, полос (страйпов). Специфическое упорядочение заряда приводит к образованию различных сверхрешеток и энергетических зон локализованных носителей в неоднородных высокотемпературных сверхпроводящих купратах. Показано, что примесные и поляронные состояния (зоны) превращаются в металлические состояния на некоторых критических уровнях легирования. Мы используем соотношение неопределенности для получения конкретных условий для МДПов в легированных купратах. Определены пределы применимости этих МДПов в купратах. Наши результаты согласуются с существующими экспериментами на основе La и других купратов.
