The 29th Ad-Hoc Workshop on Jana2006: Basics

Workshop / Čt, 04/02/2016 - 09:00 - Pá, 05/02/2016 - 18:00

V. Petříček, M. Dušek

Workshopy "Ad hoc" o programu Jana2006 jsou dvoudenní akce pořádané autory krystalografického programu Jana2006. Účastníci workshopu si sami vybírají témata, která jsou vyvěšena na webové stránce jana.fzu.cz, a workshop se koná, jakmile se několik osob shodne na výběru témat.

Surface engineering of indirect bandgap semiconductor nanoparticles for enhanced optical properties

Seminář / Čt, 04/02/2016 - 13:00 - 14:00

Katerina Dohnalova (Institute of Physics, University of Amsterdam, Science Park 904, 1018XH Amsterdam, The Netherlands)

IV-group bulk crystalline semiconductors, Diamond (C), Silicon and Germanium, all possess diamond structure and indirect bandgaps. The latter property results in very poor emission and band-edge absorption, limiting their use in optoelectronic and photonic applications. In nanocrystal form, oscillator strength is enhanced via the spatial confinement of carriers, which leads to relaxation of the k-selection rule and band-mixing.

Anomalous Hall Effect in antiferromagnets

Seminář / Út, 09/02/2016 - 10:00 - 11:30

Karel Výborný (FzÚ)

(Přednáška o článku Nature 527, 212 (2015) ze série Journal Club.) The common notion that the anomalous Hall effect (AHE) is propor- tional to magnetisation M suggests that antiferromagnets with M = 0 should exhibit no AHE. Despite this intuition, when certain symmetries are broken, AHE was still predicted to appear in multi-sublattice antiferromagnets with M = 0 (such as IrMn3 or Mn3Sn). Re- cently, this prediction has been confirmed experimentally and the magnitude of AHE was even found to exceed that of ordinary ferromagnetic metals.

Workshop užití programu FullProf

Workshop / Pá, 19/02/2016 - 10:00 - 15:00

František Laufek (Fyzikální ústav)

Krátká instruktáž použití volně šiřitelného programu umožňujícího zpřesňování atomové struktury z práškových difrakčních dat (rtg./neutrony). Úvodem bude představena Rietveldova metoda obecně a poté budou účastníci seznámeni s implementací této metody programem FullProf na příkladech zpřesňování atomových struktur a kvantitativní fázové analýzy.
