Application


  • Negative Differential Resistance (NDR) Memristors: Silver iodide is used in the development of bulk memristors exhibiting negative differential resistance (NDR). These memristors are essential for creating non-volatile memory devices and neuromorphic computing systems. The compositional tuning of AgI memristors has been shown to enhance their performance, making them vital components in advanced electronic applications (Naik and Rabinal, New Journal of Chemistry, 2021).
