The temperature dependence of electrical conduction in discontinuous gold films

Electronic phenomena in nanodispersed thin films

“…An additional possibility to test both the models is given by experimental data on the electron energy distributions, the electron emission stimulated by infra-red irradiation and the light emission from IMFs. From the electron energy distributions, the electron gas temperature within the emission centers was estimated at a few thousand kelvin [9,32]. This value agrees with the theoretical predictions of the model of hot electrons and with the electron temperatures evaluated by other methods [9,[32][33][34][35].…”

“…The position of the electron emission centres can be visualized on a cathodoluminescent screen. The comparison of these two images shows unambiguously that electrons and photons are emitted from the same centres [9]. Electron microscopic investigations have revealed that the emission centres are located within the current channels [10].…”

“…From the electron energy distributions, the electron gas temperature within the emission centers was estimated at a few thousand kelvin [9,32]. This value agrees with the theoretical predictions of the model of hot electrons and with the electron temperatures evaluated by other methods [9,[32][33][34][35]. In particular, the evaporation of BaO overlayers onto island films was found to lead to a significant increase of the conduction current and to a much stronger (by several orders of magnitude) growth of the emission current [5].…”

Formation of Metallic Electrical Conduction in Films of Vacuum Condensates of Metals

“…плівок, принаймні, до товщин 5-6 нм, є достатньо обґрунтованим. Одержаний результат не супере-чить результатам досліджень [34][35][36][37][38][39], в яких вивчено електронну будову острівцевих плівок міді і золота методом фотоелектронної спектроскопії. У роботах [39,40,41] показано, що в плівках цих металів (зокрема, Ni та Pd) формування зонної структури, аналогі-ФОРМУВАННЯ МЕТАЛЕВОЇ ЕЛЕКТРОПРОВІДНОСТІ У ПЛІВКАХ МЕТАЛІВ 541 чної електронній структурі масивного металу, завершується при лінійних розмірах зерен біля 5 нм.…”

A composite system of metal particles in a dielectric matrix for use as a thermoresistor†

“…A system of metal particles (islands) on a dielectric substrate shows a rather high thermal coefficient of resistivity provided the particles are closely positioned and form a specific structure (Borziak et al 1981). These films are usually produced by means of vacuum deposition.…”
