This is due to its ability to measure high spectrum of frequencies (range of 50 Hz to 1 MHz) and corresponding values of resistance, impedance, phase angle, quality factors, as well as to give better information about material's behaviour. KEY WORDS: RCL meter, electrode, electric properties 1. INTRODUCTIONNowadays, the thin layered materials and structures present the essential components oftechnical progress and industrial application. The interest about thin films and structures reaches. back to the 20th century, as does the increase in the strong research of new materials and technologies [1-3], mainly in 9ptics and optical applications. Requirements of the miniaturization of semiconductors· electronics and the new technologies in electronics are bounded to physics of thin films. Physics orientation on low dimensional structure researches theirproperties and application in connection with a strong support in nanoresearch, what leads to better knowledges and solutions. However, the achievements of the basic and application research arouse illusions, hypothesis, unexpected investigations ... Materials today -r Ceramics, fabric glass, metals, alloys, intermetallic, polymeric materials - organic, inorganic, Semiconductors Si, Ge ... Composites, hybrid materials Nanomaterials ! NEW MATERIALS! Study of material chemistrý consists of a preparation of compounds with required: Morphology, form, particle size, porous Crystallinity - amorphous, crystalline 50
