Abstract

The Zinc Oxide (ZnO) has been showing a very promising material for applications in electronic devices such as in catalysis, chemical sensors, solar cells, the methanol synthesis, photocatalysis, light emitting diodes, UV laser diodes and microsensors. There are many reports of syntheses of nanoparticles and them have presented different properties, being found in the most distinct forms, such as nanorods, nanowires, nanotubes, nanodisks and nanospheres. For this reason, they are open the possibility of new lines of application of these materials. Among these, the manufacture of TCOs (transparent thin films), anode batteries, photoelectrochemical, and photovoltaic photodetectors. There are many papers about compounds ZnO, both as a pure material with doping, interfaces, nanotubes, always aiming to improve and optimize the application of ZnO in general, such as electronic devices. Currently, a material is studied as well as its synthesis, there is also a growing concern with the cost of production and its efficiency, in this case, electronic efficiency. Thus, there is a increasing interest in the application of computational chemistry to studies which indicate the best way to improve the material for a particular application, however, there are few theoretical papers in the literature, particularly with respect to ZnO. For this reason, this project aims at the detailed study of structural, electronic and mechanical properties of pure ZnO doped with transition metals and interfaces of materials with the same structure, and the systematic analysis of surfaces and nanotubes, pointing out the main characteristics arising from these changes.
