Analysis of New Opotoelectronic Device for Detection of Heavy Metals in Corroded Soils

Abstract

This study was made to design and an analysis the purpose of novel optoelectronic sensor, with three steps, being the first the use of MatLab software to simulate with a mathematical equation, the operation of the sensor as the electrical conductivity. Other step, was the evaluations with Wein2k using the Density of States (DOS) Theory, as a computational system of the physicochemical, to analyze different materials used, to fabricate the novel sensor, being the material proposed the Gallium Nitride (GaN), in according to the electrical conductivity, and was obtained, to fabricate this type of material with the Chemical Vapor Deposition (CVD) and then was made some evaluations to validate this material. Also was made a microanalysis with the Scanning Electron Microscopy (SEM) to evaluate the metallic surfaces of the electrical connections at micro scale.
