The 29th Ad-Hoc Workshop on Jana2006: Basics

Workshop / Thu, 04/02/2016 - 09:00 - Fri, 05/02/2016 - 18:00

V. Petříček, M. Dušek

Ad hoc workshops are small two days workshops organized by authors of the crystallographic software Jana2006. The topics and dates are selected by participants in Jana web pages jana.fzu.cz. A workshop is organized as soon as an overlap in subscribed topics is found.

Surface engineering of indirect bandgap semiconductor nanoparticles for enhanced optical properties

Seminar / Thu, 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

Seminar / Tue, 09/02/2016 - 10:00 - 11:30

Karel Výborný (Institute of Physics ASCR)

(A Journal Club Lecture.) The common notion that the anomalous Hall effect (AHE) is proportional to magnetisation suggests that antiferromagnets with zero magnetisation should exhibit no AHE. Despite this intuition, when certain symmetries are broken, AHE was still predicted to appear in multi-sublattice antiferromagnets with zero magnetisation (such as IrMn3 or Mn3Sn). Recently, this prediction has been confirmed experimentally and the magnitude of AHE was even found to exceed that of ordinary ferromagnetic metals.
