The use of halide perovskites in solar cells and other devices continues to attract the attention of researchers worldwide, and efficiencies in energy conversion of almost 30% have been reported. A current limitation for the proper commercialization of these devices is the reduced stability of the involved materials, which are relatively unstable to exposure to moisture causing phase sepa…
Research in the field of Materials Science has advanced enormously in recent years, from an essentially applied, engineering-related approach to a position where it has great impact in other areas, including Physics, Chemistry, and Biology. This is mostly due to the advancement of theoretical and experimental techniques that have allowed us to probe, and interact with matter at the atomic…
Nanotechnology offers conventional electronics in miniature side, as well as a wide range of completely new devices that allow control of electronic, optical, magnetic, structural, or mechanical properties by external "switching" via external perturbations, such as electric or magnetic fields, illumination, or mechanical deformation. A lot of this has already been realized in single atom …
A significant improvement in quality of life of mankind in recent times has been achieved through the development of new materials in various areas of science. The unimaginable technological advances of recent decades has allowed engineering to improve the preparation and characterization of new nanostructured and massive materials, with the concomitant production of new electronic, magne…
The objective of this project is to develop a collaborative scientific interaction between researchers from Brazil and Colombia in the area of Materials, nanoscience and nanotechnology.

Two-dimensional materials can have unique electronic and magnetic properties that make them attractive in researching new materials. Currently we have several new 2D compounds among which the most studied are graphene, phosphorene, silicene, germanene and MoS2. There is in the scientific community the prospect that other stable two-dimensional materials can still be discovered, always see…
This project aims to develop theoretical/computational studies on interfaces between different semiconductor materials. This type of interface is of fundamental importance for the development of a number of devices, including transistors and solar cells. We will use theoretical methods based on density functional theory to understand the main properties of a series of interfaces, starting…
Hybrid perovskites may supply the growing needenergy consumption combined with the depletion of resourcesfrom non-renewable sources due to its superior characteristics in applicationsin solar cells, in addition to their possible applicationsin energy storage devices and in sensors and LEDs. Additionally, these materials serve as a platformfor the study of physical mechanisms, such as Rash…
Quantum effects control many of the properties of materials and, sometimes, these effects lead to the discovery of unusual phenomena. Materials that present these characteristics are usually classified as quantum materials. One of these unusual behaviors is the existence of anti-doping in some compounds. Instead of increasing the conductivity, doping leads to an increase of the resistivit…
Hybrid perovskites have been largely studied for application in solar cells, LEDs and other electronic devices. They are materials with simple synthesis, low cost and high performance that makes them a promise for clear energy and a substitutional technology for silicon. Even though the large number of studies in their properties, there are several aspects misunderstood and associated wit…

Halide perovskites belongs to the semiconductor materials class with a high potential for applications in photovoltaics devices, especially in solar cells. The low cost of production, easy fabrication and the high performance makes this materials the possible candidates to replace the actual technologic based on silicon. However, high degradation issue in moisture environment, high temper…
Alternate organic-inorganic stacking forming two-dimensional hybrid organic-inorganic perovskites is way to overcome stability issues associated to their three-dimensional counterparts. Substituting the toxic Pb atoms by others is also a way to solve another major drawback in traditional perovskites. To address these issues while searching for new functional materials mainly envisaging sp…
In the past decades, the development of electronic structure methods, mainly within the formalism of Density Functional Theory, has evolved in terms of predictive power and efficiency, being highly spread over the entire field of materials modelling and condensed matter physics and providing a large support for understanding and complementing experimental efforts in this area. When couple…
The candidate currently has a postdoctoral scholarship from FAPESP. Upon request of this scholarship, we have explicitly mentioned the intention for him to spend one year abroad developing the project with our international collaborator, Prof. Alex Zunger. This project is based on the idea that quantum effects emerging by virtue of the interface itself can be directly used to control the …
Computer simulations are a powerful way to design new materials. Computer simulations can be used to predict new materials with specific properties or to explain new phenomena observed in the laboratory. This area had an enormous advance in the last decades, recently reaching its maturity. This advance opened new frontiers in the field, and one of these is the treatment of huge quantities…
