Abstract
Prussian blue (PB) layers were electrodeposited for the fabrication of Au/PB/Ag stacks to study the resistive switching effect. The PB layers were characterized by different techniques to prove the homogeneity, composition, and structure. Electrical measurements confirmed the bipolar switching behavior with at least 3 orders of magnitude in current and the effect persisting for the 200 cycles tested. The low resistance state follows the ohmic conduction with an activation energy of 0.2 eV.

The continuous evolution and improvement of electronic devices have led to new emerging challenges
We report the structural properties of electrodeposited Prussian blue (PB) films with controlled cube morphology
The electrochemical deposition of the PB films was performed in potentiostatic mode at room temperature by using Au/Cr/Si substrates as working electrodes, a Pt foil as a counter electrode, and a saturated calomel electrode (SCE) as reference
Summary
The continuous evolution and improvement of electronic devices have led to new emerging challenges. Many alternatives have been proposed over the years to improve technology, especially in the electronic field. As the scale for miniaturization increased for electronic devices, different problems related to physical limitations appeared [2,3]. The field of material science and device structures, and other physical phenomena were studied. In this sense, a new effect, known as resistive switching (RS), has emerged as an alternative physical mechanism to be implemented in many different applications [4,5]. Devices in which the RS effect occurs are known as memristive devices [6]
