Abstract

For the first time temperature dependence of optical energy gap of antimony sulfoiodide (SbSI) nanowires has been determined. In ferroelectric phase (for 241 K < T < T_c = 292 K) the evaluated indirect forbidden optical energy gap has been fitted by E_gfI(T) = [2.195(3) - 10.8(1) × 10^-4T] eV. In paraelectric phase (T_c = 292 K < T < 344 K) the energy gap has been described by E_gfI(T) = [2.152(4) - 9.3(1) × 10^-4T] eV. It has been estimated that at the temperature of 240 K the spontaneous polarization of the SbSI nanowires has the maximum value of about 0.08 C/m².
