Title: Perovskite CsPbBr 3 Single Crystal Detector for Alpha-Particle Spectroscopy.

Abstract

Here we report the first spectroscopic alpha particle detection based on CsPbBr 3 detectors with asymmetric contacts. The CsPbBr 3 single crystal was grown from melt using Bridgman method and then fabricated into detectors with different contacts. The In/CsPbBr 3/Au detector presented a low dark current (~100 nA/cm 2) and temporal stable performance under high electric field (1000 V/cm). Such detector demonstrated excellent gamma ray resolving capability with a full-width at half maximum (FWHM) of ~5.9 keV for the 57Co 122 keV γ ray. The CsPbBr 3 detector was capable of simultaneously resolving both the alpha particle (5.5 MeV) and γ ray (59.5 keV) peaks from 241Am radiative isotope. The transport properties of CsPbBr 3 were then determined based on the alpha particle spectra and corresponding rise time distributions. The equivalent values of electron and hole mobilities were indicated as 63 and 49 cm 2/(V∙s) respectively. The calculated electron and hole mobility-lifetime products were 4.5 x 10 -4 and 9.5 x 10 -4 cm 2/V, respectively, demonstrating superior transport properties of holes over electrons in CsPbBr 3. As a result, this work widens the scope of perovskite detectors to encompass charged radiation as well as high energy X/γ rays, andmore » will significantly promote and guide further studies on perovskite materials for radiation detection applications.« less
