Fotoferroelektryczne zjawiska w monokryształach $(Ba, Sr) Nb_2O_6$
(1990)
Influence of illumination on phase transition temperature, on dielectric permittivity and on pyro currents in $Ba_xSr_{1-x}Nb_2O_6$ was studied. Dependence of photoelectretic charge density on temperature in the region of ...
Zależność między szerokością pasma wzbronionego a temperaturą Curie w ferroelektrycznych roztworach stałych ze strukturą typu perowskitu
(1990)
On the base of the spectral dependence of the photoconductivity the width of forbidden band E[g] was determined in ferroelectric solid solutions: x PbTiO[3] – (1-x)SrTiO[3] I, x PbTiO[3] – (1-x)PbZrO[3] II, AgNbO[3] – ...
