This work presents the fabrication process of an intelligent thin film from a hybrid compound to realize transparency and flexibility characteristics. Various delicate operations are encountered during preparation of the film such as exposition to radiations and baking in vacuum oven for many times. The built film with specifics materials improves the performances. The phase quality depends on the type of additives materials during preparation. The band gap of the film is controlled to permit reliability of the fabricated film and endurement of temperature variations. The fabricated thin film can be an alternative and crucial solution for many smart devices that are influenced by blazing and glazing limits. This work also parallelly represent the characteristics such as electrical impedance in function of temperature and optical reflection coefficient.
This paper discusses the simulation and experimentation of innovative minerals and metals detector to improve the performances of old systems. Indeed, actual detectors are limited concerning depth, sensitivity and selectivity. We propose here to implant helical antenna on shell points of two coils to boost detection process by increasing directivity gain and reflexion coefficient. The system uses the principle of electromagnetic induction and beat frequency oscillator (BFO) and contains search coil to detect metals and minerals at appropriate range and gives an auditory and vibratory indication once the element is detected. The search coil forms part of an LC oscillation circuit linked to added helical antenna. The activation frequency of the LC oscillator is primarily determined by the value of involved inductor and capacitor to recover the large gamme of frequencies and detect more kind of materials.
This work discusses the development of innovative transistor from intelligent thin film. A developed semiconductor junction that constitutes the core of concepted transistor is being studied. Each technology of semiconductors has shortage of some performances. The recent work is an alternative by exploiting intelligent materials to build a transistor with transparency and flexibility characteristics. Many processes are encountered during preparation of the film especially chemical deposition and exposition to laser beam to ensure dopants integration. The physical phase is a challenge for newest technology like the plasma. Thereon, we give a real example of smart thin film. The band gap is also a defiance that we are reducing to ameliorate precisely the impedance and thickness and keep at order of nanotechnology. The fabricated junctions are tested by studying their operation in ordinal conditions. We judge the quality of junctions and transistor from their optical properties and electrical ones. Moreover, we analyze evolutions of electrical impedance in function of temperature and optical reflection coefficient.
