Special Issue Information

Dear Colleagues,

Solid-state reactions in nanomaterials offer tremendous opportunities to create new materials with unique properties. The specific structure of nanomaterials, characterized by a large number of grain boundaries (or a large surface area) and, as a rule, crystalline defects, provides diffusion rates that are orders of magnitude higher than those in bulk materials. Therefore, solid-state reactions proceed much faster and require much less energy to activate.

This Special Issue aims to study the kinetics and mechanisms of solid-state reactions in metals and semiconductors; develop methods of solid-state synthesis; study the structure and properties (magnetic, optical, electronic, thermoelectric, etc.) of nanomaterials obtained by solid-state reactions, including nanostructures grown on the surface of bulk materials; and to model and theoretically describe the processes which occur during solid-state reactions involving nanomaterials.

The Special Issue is dedicated to the memory of a remarkable man and bright scientist, Dr. Victor Myagkov, who spent many years studying the nature of solid-state reactions and magnetism in thin films.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Solid-state reactions in nanomaterials (nanolayers, thin films, nanoparticles, etc.);
  • Interfacial reactions;
  • Kinetics of solid-state reaction;
  • Combustion synthesis;
  • Metal-induced crystallization;
  • Nanojoining;
  • Modeling of solid-state reaction.

Nanometric multilayers composed of immiscible Ag and Ni metals were investigated by means of molecular dynamics simulations. The semi-coherent interface between Ag and Ni was examined at low temperatures by analyzing in-plane strain and defect formation. The relaxation of the interface under annealing conditions was also considered. With increasing temperature, a greater number of atomic planes participated in the interface, resulting in enhanced mobility of Ag and Ni atoms, as well as partial dissolution of Ni within the amorphous Ag. To mimic polycrystalline layers with staggered grains, a system with a triple junction between a silver single layer and two grains of nickel was examined. At high temperatures (900 K and 1000 K), the study demonstrated grain boundary grooving. The respective roles of Ni and Ag mobilities in the first steps of grooving dynamics were established. At 1100 K, a temperature close but still below the melting point of Ag, the Ag layer underwent a transition to an amorphous/premelt state, with Ni grains rearranging themselves in contact with the amorphous layer.

High-entropy alloys are promising materials for novel thin-film resistors since they have high resistivity and a low-temperature coefficient of resistivity (TCR). In this work, a new high-entropy thin-film CoCrFeNiTix was deposited on a Si/SiO2 substrate by means of magnetron sputtering of the multi-component target produced by hot pressing of the powder mixture. The samples possessed a thickness of 130–230 nm and an amorphous atomic structure with nanocrystallite traces. This structure persisted after being annealed up to 400 °C, which was confirmed using X-ray and electron diffraction. The film had a single-phase structure with a smooth surface and a uniform distribution of all elements. The obtained film served for microresistor elaboration, which was produced using the lithography technique and tested in a temperature range from −60 °C up to 200 °C. Resistivity at room temperature was estimated as 2.37 μOhm·m. The results have demonstrated that TCR depends on temperature according to the simple linear law in a range from −60 °C up to 130 °C, changing its value from −78 ppm/°C at low temperatures to −6.6 ppm/°C at 130 °C. Such characteristics show the possibility of using these high-entropy alloy films for resistive elements in contemporary and future micro-electronic devices. Full article
