“…This device exhibited plenteous potential for NVM due to its exceptional piezo-electric and resistive switching performance. Lot of exploration is ongoing for materials such as zirconium dioxide (ZrO 2 ) [14,15], hafnium oxide (HfO x ) [8,[16][17][18][19], zinc oxide (ZnO) and titanium oxide (TiO x ) [9,20], poly(4-vinylphenol) (PVP) [21], polyvinylpyrrolidone [22], poly(methyl methacrylate) [23], poly(vinyl alcohol) (PVA) [24], polystyrene, surface-supported metal−organic frameworks [25], graphene oxide (GO) [26,27], reduced GO [27], molybdenum disulfide (MoS 2 ) [5,12,[28][29][30], and hexagonal boron nitride (hBN) [31,32] are the few among them. The major key challenges for ReRAM devices that are mostly addressed in the literature are retention, endurance, ON/OFF ratio and operating voltage.…”
