Fabrication and characterization of SbSI gel for humidity sensors

Growth of large SbSI crystals

“…The values of E a = 0.341(55) eV and E a = 0.236(22) eV have been determined for E⊥c in cases of ferroelectric and paraelectric phases of SbSI, respectively. The E a = 0.441 (12) eV and E a = 0.339(22) eV have been established for E c in the same cases.…”

“…The main properties of SbSI were reviewed in a few monographs [1][2][3][4][5][6]. However, the properties of this material have been still investigated [7][8][9][10][11][12][13]. Due to these properties, SbSI is an attractive and suitable material for thermal imaging [3,4,[14][15][16][17], light modulators [3,4,18], ferroelectric field effect transistors (FeFET) [19,20], gas sensors [21], piezoelectric elements used in certain types of electromechanical transducers [4,[22][23][24], temperature autostabilized nonlinear dielectric elements (TANDEL) [25,26], time-controlling devices [3,4,27] and other applications.…”

SbSI Single Nanowires as Humidity Sensors

“…Humidity nanosensors were constructed from single SbSI nanowires sonochemically prepared [2] and welded ultrasonically to Au interdigitated microelectrodes (with l = 1 µm spacing), according to the technology described in [4]. After switching illumination on, the electric photoconductivity current increases fast, attains maximum, and then slowly decreases with time to a stationary value.…”

“…SbSI Single Nanowires as Humidity Sensors Recently, the inuence of humidity on impedance spectra [1], electrical conductivity [2] and photoconductivity transient characteristics [3] of SbSI gel, made up of large quantity of nanowires, has been investigated. In order to complete investigations of the observed phenomena, the experiments with single SbSI nanowires are analyzed in this paper.…”

Mobility of Ferroelectric Domains in Antimony Sulfoiodide

“…Antimony sulfoiodide (SbSI) is a promising semiconducting [3] ferroelectric [4] with many interesting properties, e.g. piroelectric, pyrooptic, electrooptic, photoferroelectric eects, and gas sensing [5,6]. Dierent optical energy gaps in ferroelectric and paraelectric phases as well as light scattering on the domain walls allow to observe ferroelectric domains in ferroelectric materials e.g.…”
