Data Storage Properties of a Device Based on Selenium-dispersed Cow Milk

Abstract

The phenomenon of resistive switching in organic materials is crucial for the advancement of devices that have a smaller environmental impact. This work aims to enhance the resistive switching characteristics of organic cow milk-based films by including selenium particles. The non-toxic nature and semiconductor qualities of selenium were the motivating factors behind the decision to utilize it in this work. Four devices were created using milk-selenium active layers with varying selenium concentrations. Upon doing the current-voltage measurements, hysteresis was discovered in all the devices, indicating memory behavior. Our results revealed that higher selenium concentrations led to a decrease in data noise and improved the stability of memory hysteresis throughout repeated measurements. Finally, when the concentration of selenium was too high, the hysteresis became distorted and lost its ability to be reproduced when measurements were repeated. This implies that the resistive switching of cow milk-based devices can be customized by precisely regulating the concentration of selenium particles.
