Optical and dielectric properties of CuInP₂S₆ layered crystals at high hydrostatic pressure

Guranich, P P; Slivka, A G; Shusta, V S; Gomonnai, O O; Prits, I P2008

[en] Effect of hydrostatic pressure on the birefringence and dielectric properties of CuInP₂S₆ crystals is studied. The pressure behaviour of the phase transition temperature confirms that the phase transition in these crystals belongs to the order/disorder type. An additional line of birefringence anomalies in the ferrielectric phase is revealed. Based on the studies of the optical and dielectric properties of CuInP₂S₆ crystals their (p, T) diagram was constructed

Hydrostatic pressure effect on the optical spectra of glass-embedded CdS_1-xSe_x nanocrystals

Shusta, V S; Slivka, A G; Gomonnai, O O; Azhniuk, Y M; Lopushansky, V V2008

AbstractAbstract

[en] Effect of hydrostatic pressure on the optical absorption spectrra of CdS_1-xSe_x nanocrystals embedded in borosilicate glass matrix, is studied. A pressure-induced blue shift of the optical absorption edge and confinement-related maxima is observed. Energy band gap pressure variation coefficients are determined, their compositional and size behaviour being discussed in view of possible structural difference within the nanocrystal ensemble
