Doping induced effect on optical and band structure properties of Sr2Si5N8 based phosphors: DFT approach

Nitrido silicates are emerged as highly efficient luminescent materials (phosphors) that found considerable industrial application as white light emitting diodes (LEDs) have been studied with respect to band structure and related electronic structure parameters. They have tunable optical properties, as&...

Elektrónová a pásová štruktúra CuMnAs študovaná optickou a fotoemissinou spektroskopiou

The tetragonal phase of CuMnAs progressively appears as one of the key materials for antiferromagnetic spintronics due to efficient current-induced spin-torques whose existence can be directly inferred from crystal symmetry. Theoretical understanding of spintronic phenomena in this material, however, ...

TAS3 Nanovlákna: vrstvený trichalcogenid pro vysoce-výkonnou elektroniku a senzory

Layered materials, like transition metal dichalcogenides, exhibit broad spectra with outstanding properties with huge application potential, whereas another group of related materials, layered transition metal trichalcogenides, remains unexplored. Here, we show the broad application potential of this interestin...

Studie konvergence izogeometrické analýzy založené na Bézierově extrakci ve výpočtech elektronových struktur

Behavior of various, even hypothetical, materials can be predicted via ab-initio electronic structure calculations providing all the necessary information: the total energy of the sys- tem and its derivatives. In case of non-periodic structures, the existing well-established methods for electronic...

Zkoumáním optoelektronických vlastností nitrido-magneso-silikátů: Ca [Mg3SiN4], Sr [Mg3SiN4] a Eu [Mg3SiN4]

Optoelectronic properties of the Nitrido-magneso-silicates Ca[Mg3SiN4], Sr[Mg3SiN4], and Eu[Mg3SiN4] compounds have been investigated using the relativistic full-potential augmented plane-wave method (FLAPW) based on the density functional theory (DFT). The calculations of the electronic and optical properties were&...

Reflexe jak vyhodnocovat profesní hodnotu vědeckých publikací a jejich citačních ohlasů

It is inevitable that the´publish or perish´ paradigm has implications for the quality of research published because this leads to scientific output being evaluated based on quantity and not preferably on quality. The pressure to continually publish results in the creation of predatory&...

Stamp metoda pro zpracování dat s vysokým podílem šumu z infračerveného senzoru v drsném prostředí

This article presents a new digital method, called Stamp method, for elimination of undesired noisedata from a periodic IR signal. The Stamp method is a useful tool for statistical analysis of changes which appear in a noised input signal. One stamp is a statistical image ...

Stanovení nejistoty ve vysokoteplotní metodě měření spektrální emisivity povlaků

The paper deals with uncertainty analyses of the new laboratory method for the measurement of spectral emissivity of high-temperature coatings. These coatings are intended to increase heat transfer in various industrial applications. The experimental set-up of the method is shortly introduced.&#x...

Diskuse k pokusům o vyvrácení Šestákovy - Berggrenovy rovnice

Some recent commentaries doubt the originality of Šesták–Berggren equation even though it received until today almost eight hundred citation responses. The worth of SB equation is examined in terms of general logistic equation showing its divergent philosophical strategy from dissimilar orthodox&...

Slabiny analýzy exergie

The well-known Gouy–Stodola theorem states that a device produces maximum useful power when working reversibly, that is with no entropy production inside the device. This statement then leads to a method of thermodynamic optimization based on entropy production minimization. Exergy destruction&#x...
