Experimentální a teoretické studie elektronické struktury a optické spektrální charakteristiky PbIn6Te10

We present measurements of the optical properties of crystalline PbIn6Te10. The samples are grown in the form of parallelepipeds of size _5 _ 3 _ 0.3 mm3. The absorption coefficient a(hn) shows an exponential behavior with energy in the energy range 0.82–0.99 eV followed by&#x...

Sensitivity analysis of the crack evaluation for steam turbine casings loaded by pressure and temperatures

The operation of steam turbines is related to the extreme conditions such as high pressure and temperature, which can lead to fatigue issues and subsequent undesirable problems. This paper is focused on the methodology for the fracture analysis of turbine casings. The evaluation me...

Optická emisní spektroskopie plasmy vzniklé laserovou ablací sulfidu železnatého

Optical emission spectroscopy studies are reported of laser ablation plasma from an iron sulphide (FeS) target in vacuum. The plasma emission is characterized with spatial and tempoal resolution. The spectral observations are used to calculate the electron plasma parameters. The electron tem...
