From September 2nd to 6th, 2024, our Nanostructure Physics Group Leader, Dr. František Karlický, attended the CMD-31 Conference (General Conference of the Condensed Matter Division) in Braga, Portugal. This five-day conference covered all aspects of condensed matter and materials physics, as well as interdisciplinary topics and the development of research infrastructure in Europe. The program…
On August 29, 2024, our PhD student Nilesh Kumar successfully defended his dissertation on the topic “Electronic and Optical Properties of Semiconducting MXenes,” thus completing his doctoral studies. We warmly congratulate our third graduate and wish him great success in his future scientific career!
Master’s student in the Teaching for High Schools program, Hana Honsejková, successfully defended her thesis on the topic “Explanation of the Probability of Electron Occurrence in High School” on August 21, 2024, under the supervision of Dr. Miroslav Kolos, thus successfully completing her Master’s degree. We extend our heartfelt congratulations to Hanka and wish her…
Strain-induced changes of electronic and optical properties of Zr-based MXenes Link here: https://doi.org/10.1063/5.0205991 Abstract: Zr-based MXenes recently attracted attention because of its experimental preparation showing temperature stability, mechanical strength, and promising energy, sensoric, and electrochemistry applications. However, necessary theoretical predictions at a precise/predictive level are complicated due to essential excitonic features and strong electron correlation…
Mn2C MXene Functionalized by Oxygen is a Semiconducting Antiferromagnet and Efficient Visible Light Absorber Link here: https://doi.org/10.1039/D4CP02264E Abstract: Manganese-based MXenes are promising two-dimensional materials due to the broad palette of their magnetic phases and the possibility of experimental preparation because the corresponding MAX phase was already prepared. Here, we systematically investigated geometrical conformers and spin…
MXene’s Surface Functionalization Patterns and Their Impacts on Magnetism Link here: https://doi.org/10.1039/D4CP01319K Abstract: Two-dimensional transition metal carbides and nitrides (MXenes) are a perspective group of materials with a broad palette of applications. Surface terminations are a product of the MXene preparation, and post-processing can also lead to partial coverage. Despite applicability and fundamental properties being…
Phonon Assisted Exciton Processes in Two-Dimensional Tungsten Monocarbide Link here: https://doi.org/10.1021/acs.jpcc.4c02062 Abstract: In this study, we utilized a rigorous ab initio-based finite momentum Bethe–Salpeter equation to investigate the photoluminescence emission in two-dimensional hexagonal tungsten carbide (h-WC). This thermodynamically stable monolayer exhibits an indirect optical gap, resulting in phonon-assisted emission. We observe that light absorption is…
