Luminescence Modes in the Semiconductor Micro Structure

Monday, 29.04.2013 13:00 - 14:00

Huibing Mao (East China Normal University, Shanghai, China)

In the semiconductor microstructure there are two different modes: Fabry-Perot modes and whispering gallery modes. In the band-edge region, there are strong coupling between the exciton and the confined photon, which will lead a quasi-particle: polariton. In a ZnO semiconductor nanobelt with a transverse size of m, more than 20 modes are observed in the band-edge region, and more than 60 modes are observed in the visible region. The theoretical results demonstrate that in the band-edge region the luminescence modes are determined by the polariton modes.

Studies of phase transitions in Fe containing ternary perovskite multiferroics

Tuesday, 07.05.2013 10:00 - 11:00

Igor P. Raevski (Southern Federal University, Rostov-on-Don, Russia)

One of the promising ways of designing new single-phase multiferroic materials is adjusting the temperatures of both ferroelectric and magnetic phase transitions by ion substitutions in the host compound to obtain the maximal magnetoelectric coupling. The aim of the present talk is a brief review of the recent studies of both ferroelectric and magnetic phase transitions in some Fe containing ternary perovskite multiferroics, especially PbFe0.5B0.5O3 (B-Nb, Ta, Sb) and related solid solutions.
