In this paper we investigate electron-beam modification and the process of subsequent recovery of phase transition parameters of VO 2 -based films within 20-100°C temperature range. It is shown that the level of electron-beam modification, i.e., resistance change value, is by an order of magnitude higher in VO 2 metallic phase compared with the semiconducting one. The time of parameter recovery in air also changes at phase transition (less than a minute for the metallic phase and more than an hour for the semiconducting one), while within each phase the temperature dependence of modification rate and recovery is negligible. The physics of the phenomena is explained by peculiarities of the processes of oxygen vacancies generation and recombination in both phases. The regularities of electron-beam modification influence on the electrical switching effect are established; particularly, the threshold voltage of switching device is found to decrease under the action of modification.

Исследованы оптические свойства новых металлодиэлектрических нанокомпозиционных материалов на основе опаловых матриц. Положение оптических резонансов нанокомпозитов, полученных введением сереб-ра в матрицу опала методом электротермодиффузии, объяснено брэгговской дифракцией, а асимметричная форма резонансных кривых -резонансом Фано.Обнаружено аномальное пропускание и поглощение света гибридными плазмонно-фотонными слоистыми гетероструктурами, связанное, по-видимому, с возбуждением поверхностных плазмон-поляритонов, распро-страняющихся вдоль границ раздела " металл−диэлектрик". Работа выполнена при поддержке Министерства образования и науки Российской Федерации (НИР № 576 в рамках базовой части государственного задания в сфере научной деятельности по заданию № 2014/700 за 2014 г.).

An experimental study of the optical properties of two types of metal-dielectric composites based on opal matrices was carried out: 1) layered structures obtained by successive deposition of metal and dielectric films on a monolayer of opal globules, where extraordinary transmission and extraordinary absorption of light were detected due to the excitation of surface plasmon polaritons of various types; 2) "massive" opal samples, which were infilled with metal by electrothermodiffusion, where an asymmetric form of Bragg resonance curves was observed, due to the Fano resonance.
