TEM-based Electron Diffraction (ED) has progressed from sample orientation or phase analysis to a reliable method for ab initio crystal structure determination at the nanoscale. Owing to the high interaction strength, the practical limits of ED applicability continue to be explored, but its limitations are apparent: only a finite dose budget can be spent on collecting diffraction patterns from...

This project builds a comprehensive understanding of Ni-Fe-Ga Heusler nanowires. These materials provide the means for transfer of the shape memory and magnetocaloric properties of Heusler alloys towards nanoscale. A single-step synthesis developed during the project and immediate functionality make the nanowires a suitable material in the field of microelectronics, cell-oriented biomedicine...

Magnonics — the study of spin waves — is a promising field for developing energy-efficient future information technologies. In this project, we explored magnon transport in altermagnetic materials, a novel class of collinear and compensated magnetic systems with unique spin symmetries that allow for many useful spintronic phenomena.

Environmental interactions are usually associated with decoherence and the loss of quantum information. However, they also play an essential role in the measurement, control, and stabilisation of quantum devices. We theoretically investigate this dual role in two open quantum systems.
The first system is a singlet–triplet qubit in a double quantum dot monitored by a quantum point contact....

Atomic size mismatch in oxide crystals has long been treated as a barrier, linked to phase instability, dopant segregation, and uncontrolled defect formation during melt growth. This project overturns that limitation by establishing ionic size mismatch and melt nonstoichiometry as controllable variables that define phase structure and functional properties in rare-earth aluminate high-entropy...

Magnetic textures have recently attracted significant theoretical and experimental interest due to their rich and complex physical properties, making them potential candidates for new computational devices. Their feasibility as a data processing unit has also recently been demonstrated. However, the current developments in this regard are confined to a very small number of magnetic textures....

GridFF, an efficient method for simulating molecules on rigid substrates. The approach is inspired by techniques from techniques used in protein–ligand docking in biochemistry. By projecting molecule–substrate interactions onto precomputed spatial grids with tricubic B-spline interpolation, GridFF reduces the computational cost by orders of magnitude compared to traditional pairwise atomistic...

Despite demonstrating bistability, the absence of long-range magnetic order and poor electrical conductivity in spin-crossover (SCO) materials limit their prospects in spintronics. Here, we report easily processable Fe-based SCO nanostructures specifically [Fe(Htrz)2(trz)]BF4 grown on 2D reduced graphene oxide (rGO). X-ray photoelectron spectroscopy (XPS) reveals a new bonding state and...

Probing charge carrier dynamics across a broad frequency range — from terahertz (THz) to infrared (IR) regimes — presents a powerful, contact-free procedure to investigate nanoscale transport phenomena in low-dimensional materials. Combining frequency dependent optical conductivity spectra with conventional d.c. electrical measurements enable a comprehensive picture of carrier transport...

Porous carbon materials are widely recognized as promising electrode candidates for supercapacitors due to their high specific surface area and tunable pore architecture, which facilitate efficient ion adsorption and enhance electric double-layer capacitance (EDLC). Furthermore, heteroatom doping, particularly nitrogen incorporation, can introduce additional pseudocapacitive contributions via...
