Ultrananocrystalline diamond (UNCD) films incorporating photoluminescent color centres have emerged as promising materials for quantum sensing applications due to their unique optical properties. This study investigates the synthesis, characterization, and enhancement of silicon-vacancy (SiV) centres in UNCD films. We successfully fabricated variously Si-doped diamond films using microwave...

increasing due to the properties of electrons such as strong interaction with matter. Procedures for the preparation of protein crystal samples for electron
diffraction as well as the subsequent processing of diffraction data are gradually
being standardized. This work deals with the optimization of crystallization... -

V této práci jsme se zaměřili na přípravu a charakterizaci tenkých vrstev vysokoteplotních supravodičů YBCO připravených metodou IJD. V rámci výzkumu jsme připravili celkem 11 vzorků ve dvou sériích, lišících se použitým materiálem substrátu: MgO a SrTiO$_3$. Jednotlivé vzorky v rámci série se lišily teplotou substrátu během depozice. Ta se pohybovala mezi 480~°C a 530~°C pro MgO sérii a mezi...

NiTi alloys are widely used shape memory alloys due to their outstanding functional properties. Preparation of bulk NiTi with fine microstructures and high resistance to plastic deformation remains a challenge. Spark plasma sintering (SPS) theoretically enables to prepare such bulk NiTi. We synthesized, using SPS, bulk NiTi samples, exhibiting cyclic superelasticity in tension when sintering...

Plasmonics is an advanced technology in the field of optical sensors. A methodology for the preparation of silver thin films suitable for plasmonics by Ionized Jet Deposition is developed. The RF Magnetron sputtering method is used for comparison as a well mastered technique. The roughness, relative permittivity and growth rate of the layers are analyzed using atomic force microscopy,...

Multiple applications (like LEDs) require growing high crystalline quality buffer layers before active region. These are the layers at the very bottom of structures, where on the boundary between sapphire and nitride many dislocations are created due to large lattice mismatch. It is important to improve the crystalline quality in this buffer layer, so that the active region has high internal...

Transition metal nitrides (TMNs) have emerged as a promising alternative to precious metals thanks to their similar optical response and the additional advantages of refractory nature and compatibility with microelectronic industry fabrication process. This presentation will discuss the optical tunability of nanomaterials based on titanium nitride (TiN) in relation to their photothermal...

Titanium nitride is often used as a protective coating due to its hardness. Ionized jet deposition has a potential to improve and diversify ways of making TiN thin films. We optimised the nitrogen pressure in the IJD chamber to suppress concentration of titanium oxide in films. We manufactured a set of films using different deposition pressures. Based on the XRD data, higher gas pressure is...

Crystal structure analysis by diffraction methods is a standard, robust technique, that allows the solution of most new crystalline materials. It works even when the data suffers from systematic and statistical errors. However, some cases can be more challenging, and standard approaches do not easily solve the problem at hand. In this talk, we will show some examples of challenging structures...
