Abstract
Shock-induced electric response of ferroelectric antimony sulfoiodide (SbSI) nanowires is presented for the first time. The sonochemically prepared SbSI nanowires have been aligned in electric field and bonded ultrasonically with Au microelectrodes. Electrical responses of such prepared samples on shock pressure of carbon dioxide have been studied. An impact pressure could be detected, since voltage is created in SbSI due to stress-induced depolarization of ferroelectric. The amplitude of the voltage pulse, generated under shock pressure of 5.9MPa, has reached 29.0(7)V, giving the extremely high electric field 3·107V/m. The response time on pressure impact was shorter than 10µs. The recovery time attained 150(5)µs. The presented SbSI nanodevice is promising for shock pressure detection as well as for application in pulsed power nanogenerators.
