The present proposal involves the preparation of a type-I heterojunction between SnO2 and Ga2O3, as well as how to combine the energy band diagrams at the interface between these oxide semiconductors for the development of electronic devices such as field-effect transistors (FETs) and heterojunction bipolar transistors (HBTs).With samples prepared in the polycrystalline form by chemical r…
The present proposal deals with the deposition of layers of tin dioxide (SnO2) and layers of quinoline derivatives (DQ), in the form of thin films, creating simple transparent devices, based on the SnO2/DQ heterojunction. The SnO2 will be deposited by sol-gel-dip-coating which leads to a material of high transparency and reasonable electrical properties. Thus, interesting luminescent and…
The proposal involves the deposition of TiO2 thin films, through the sol-gel-dip-coating technique, which will be combined with layers of quinoline derivatives, deposited by dip-coating. Previous results show the difficulties of deposition of these organic compounds in the form of thin films by this process, although they point to the way in this direction. Thus, alternatively, the quinol…
The present proposal deals with the deposition of layers of zirconium oxide (ZrO2), oxide with insulating characteristics, via sol-gel (chemical process). In addition to the investigation of these layers, it is also proposed to combine with SnO2 layers creating a simple transparent device, based on the SnO2/ZrO2 heterojunctions. The main idea of the project is the use of these oxides for …

The work currently carried out in Brazil (UNESP, Bauru) involves two materials, an inorganic semiconductor: titanium dioxide (TiO2), with n-type conductivity, and an organic compound: the quinoline derivative (QD), which may present p-type conduction, depending on the groups attached to the main chain. The QD has interesting electro-optical properties, such as luminescence in the blue ran…
The general project of doctorate comprises the investigation of the transport properties in the SnO2/GaAs heterostructure, which has opened possibilities to several specific projects to which we have devoted in recent years, and that includes this research training at Paul-Drude-Institut,in Berlin, Germany, under supervision of Dr. Paulo V. Santos. The work being developed is based on the…
