Highlights
Gallium oxide pushes the limits of silicon for power electronics May 25, 2022 Editor’s Choice and one of the most downloaded papers of the ‘Materials’ (MDPI) journal in the first five months of the year, this review discusses the application of ultra-wide bandgap semiconductors in power electronic devices, focusing in particular on gallium oxide. | |
A new theoretical approach reveals the emergence of complex self-organised structures in spin crossover materials January 31, 2022 Researchers from GEMaC laboratory have developed an effective electro-elastic model to simulate phase transitions in spin crossover crystals. The resolution of this model is 50 times faster than the traditionally used model, which has allowed them to reveal a wide variety of complex phenomena. | |
A series of discoveries about the incredible conductive and transparent materials known as vanadates. November 14, 2021 Strontium and calcium vanadates (SrVO3 and CaVO3) are perovskite oxides. They are materials with multiple potential functions and applications. Here is an overview of recent advances, to which GEMaC has made a major contribution. | |
A material conducts to a bright future September 17, 2021 GEMaC researchers show how the conductivity of the spinel material ZnGa2O4 can be controlled over a very wide range, opening up applications in ultra-high power electronics and deep ultraviolet optoelectronics. | |
A new crystal phase in semiconductor nanowires June 25, 2021 GEMaC researchers, in partnership with the LEM (CNRS-Onera), have produced and characterised an original and unexpected crystal structure in nanoscale zinc sulphide (ZnS) wires. |
