In this thesis we address the description of electrical transport properties of disordered conductor-insulator composites, mostly by numerical Monte Carlo simulations and analytical study of realistic tunnelling-percolation models. Such composites are basically constituted by conducting particles dispersed in an insulating matrix and present a conductor-insulator phase transition, with critical...

We have measured the current noise of silver thin-film resistors as a function of current and temperature and for resistor lengths of 7000, 100, 30, and 1 mm . As the resistor becomes shorter than the electron-phonon interaction length, the current noise for large current increases from a nearly current independent value to the interacting hot-electron value s p 3y4d2eI . However, further reduc...

The paper deals with reliability evaluation procedure of thick film inductors manufactured by various techniques. Thick film inductors belong to the specific electronic passive components, which properties are known as a component „tailored“according to the application, structure and construction. Evaluation methodology principle of thick film inductors issues from entities of standardized reli...
