Synthesis and optoelectronic properties of Perovskite nanowire

We have developed a simple solution based synthesis method of CsPbI3 nanowire. This method produces high yield nanowire with controllable length and diameter. We studied in details the effect of various growth conditions, such as temperature and time on the morphology of these nanowires. Single nanowire devices were made to investigate their individual property. To understand different mechanisms that play a major role in determining the performance and stability of these nanowire devices, we studied optoelectronic and noise characteristics under various conditions. These nanowires are structurally stable under ambient condition and show stable photoresponse. We will discuss in details the possible growth mechanism and the observed optoelectronic properties of these nanowires.
