“…Using the method presented in Nowak et al (2009a), the energy gap of SbSI in the composite was determined. Value of this energy gap E g = 1.835(23) eV is in good agreement with results presented previously for SbSI (Nowak et al 2008). For wavelengths higher than 700 nm, the presence of cellulose fibers causes monotonous decrease of cellulose/SbSI reflectance coefficient.…”

Novel piezoelectric paper based on SbSI nanowires

et al. 2017

A novel piezoelectric paper based on antimony sulfoiodide (SbSI) nanowires is reported. The composite of tough sonochemically produced SbSI nanowires (with lateral dimensions 10-100 nm and length up to several micrometers) with very flexible cellulose leads to applicable, elastic material suitable to use in fabrication of, for example, piezoelectric nanogenerators. For mechanical energy harvesting, cellulose/SbSI nanocomposite may be used. Due to its high values of electromechanical coefficient (k 33 = 0.9) and piezoelectric coefficient (d 33 = 1 9 10 -9 C/N), SbSI is a very attractive material for such devices. The preliminary investigations of a simple cellulose/SbSI nanogenerator for shock pressure (p = 3 MPa) and sound excitation (f = 175 Hz, L p = 90 dB) allowed to determine its open circuit voltage 2.5 V and 24 mV, respectively. For a load resistance equal to source impedance (Z S = 2.90(11) MX), maximum output power density (P L = 41.5 nW/cm 3 for 0.05-mm-thick sheet of this composite) of the cellulose/SbSI nanogenerator was observed. Cellulose/SbSI piezoelectric paper may also be useful to construct gas nanosensors and actuators.

“…Characterization of the SbSI gel was accomplished using other techniques, such as X-ray powder diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), and selected area electron diffraction (SAED). The equipment and procedures were the same as presented by Nowak et al (2008Nowak et al ( , 2014.…”

For the rst time the thermal desorption of H2, N2, O2 and CO2 is presented for antimony sulfoiodide (SbSI) xerogel made up of large quantity nanowires. The desorption has been observed near ferroelectric phase transition established at Tc = 293.0(2) K. The Sievert measurements have shown that the hydrogen uptake is linear function of H2 pressure (when p < 1.1 × 10 5 Pa). The hydrogen storage density in SbSI gel amounted 1.24 × 10 −2 wt% (for p = 1.08 × 105 Pa at room temperature).

“…Other less common techniques, such as sonochemical synthesis 126,127,162,122 and electrophoretic deposition 71 , have also been employed for the 75 synthesis of ferroelectric nanowires and nanorods. Ramesh et al 163,164 introduced the concept of focussed ion beam (FIB) milling for the 'top-down' fabrication of ferroelectric nanostructures.…”

Ferroelectric nanoparticles, wires and tubes: synthesis, characterisation and applications

2013

Nanostructured materials are central to the evolution of future electronics and information technologies. Ferroelectrics have already been established as a dominant branch in the electronics sector because of their diverse application range such as ferroelectric memories, ferroelectric tunnel junctions, etc. The on-going dimensional downscaling of materials to allow packing of increased numbers of components onto integrated circuits provides the momentum for the evolution of nanostructured ferroelectric materials and devices. Nanoscaling of ferroelectric materials can result in a modification of their functionality, such as phase transition temperature or Curie temperature (TC), domain dynamics, dielectric constant, coercive field, spontaneous polarisation and piezoelectric response. Furthermore, nanoscaling can be used to form high density arrays of monodomain ferroelectric nanostructures, which is desirable for the miniaturisation of memory devices. This review article highlights some research breakthroughs in the fabrication, characterisation and applications of nanoscale ferroelectric materials over the last decade, with priority given to novel synthetic strategies
