Resistive Switching in Biocompatible Glucose Films Doped With Honey for Highly Flexible Nonvolatile Memory Application

A mixture of honey and glucose (GH) as a new natural biomaterial for resistive random access memory (RRAM) switching layer on polyethylene terephthalate (PET) substrate is presented. The flexible substrate allows the devices to be bent and used for a wider range of applications. These devices with the GH film exhibit good reproducibility and reliability over more than 300 cycles. Moreover, the ON/OFF ratio of these devices is over 105, and
$V_{\mathrm {SET}}$
and
$V_{\mathrm {RESET}}$
are lower than that of the device with a pure glucose film. The nonvolatile nature of the devices is confirmed by measuring retention for 104 s. This switching behavior is attributed to ohmic conduction and trap-controlled space charge-limited current (TC-SCLC) mechanisms that confirm filament formation and breakage at high-resistance state (HRS) and low-resistance state (LRS), respectively.
