Dr. Szpakiewicz-Szatan earns PhD at WUT Thursday, 24 April 2025 18:18 |
Congratulations to Dr. Eng. Aleksander Szpakiewicz-Szatan on receiving his academic title. On March 21, 2025, he successfully defended his doctoral dissertation at the Faculty of Physics of the Warsaw University of Technology (WUT), titled: "Nanocomposites from pressure-formed sodium-phosphate and bismuth glasses for applications in energy storage and conversion devices." A summary of the dissertation is available at the provided link. More information here.
Supervisors: Prof. Jerzy Garbarczyk, (Faculty of Physics, Warsaw University of Technology) and Prof. Sylwester Rzoska (Institute of High Pressure Physics, Polish Academy of Sciences). The conferment of the PhD degree was approved today (April 24, 2025), by the Scientific Discipline Council of the Faculty of Physics, WUT. The dissertation was developed as part of an ongoing collaboration between the NL-10 Laboratory (X-Press Matter) at the Institute of High Pressure Physics, PAS, and the Solid State Ionics Division of the Faculty of Physics, WUT. This collaboration will continue under a joint research grant. IHPP PAS Seminar on Nitride SemiconductorsTuesday, 22 April 2025 19:16 |

ICSM 2025 conferenceWednesday, 05 March 2025 10:57 |
10th International Conference on Superconductivity and Magnetism - ICSM 2025 will be held in Fethiye-Oludeniz, Turkey from 26th April to 3rd May 2025. This conference will cover a wide range of physics topics, including superconductivity, magnetism, and quantum materials and technological communities, and create networking opportunities and strengthen connections between all career levels. This year again, Dr. Shiv Singh from our Institute is organizing a special session: “Advances in Iron-based Superconductors: Growth, fundamental and applied research”. You can find more details about this session here. Furthermore, in this conference, Dr. Shiv Singh will have an invited talk entitled "Impurity Effects on the Superconducting Properties of Stoichiometric CaKFe4As4 by Conventional and High-pressure Growth Methods”. Recently, Dr. Singh’s research team has proved that the high-pressure growth technique can be an effective method to enhance the superconducting properties of high-Tc superconductors as well as the sample quality. More details about the program and the speakers can be found here.

We are pleased to inform about the work on spontaneous and piezoelectric polarization published recently in Materials: P. Strak, P. Kempisty, K. Sakowski, J. Piechota, I. Grzegory, E. Monroy, A. Kaminska, S. Krukowski, Spontaneous and Piezo Polarization Versus Polar Surfaces: Fundamentals and Ab Initio Calculations, Materials 2025, 18(7), 1489; https://doi.org/10.3390/ma18071489 The study discusses the fundamental properties of spontaneous and piezoelectric polarization as well as surface polarization. It has been shown that Landau’s definition of polarization as dipole density can be applied to infinite systems. Two components of polarization were distinguished: bulk polarization and surface polarization. This division is consistent with numerous experimental data. A local model of spontaneous polarization was introduced and used to calculate spontaneous polarization in the form of electric dipole density. This model correctly predicted the values of spontaneous polarization for wurtzite-type nitride semiconductors. At the same time, the model showed zero polarization for the zinc blende lattice. The values of spontaneous polarization obtained for wurtzite group III nitrides were consistent with previous calculations carried out using the Berry phase method. First-principles calculations for wurtzite nitride superlattices using the Heyd–Scuseria–Ernzerhof approximation were performed to calculate polarization fields in regularly strained lattices, showing good agreement with the polarization results. These data were used to determine the piezoelectric parameters of wurtzite nitrides, yielding values consistent with earlier results.
