Glancing angle deposition technique was used to fabricate Ag nanoparticles (NPs) capped TiO 2 Nanowire (NW) array structure for capacitive memory application. Electron microscopes confirmed the sandwiched structure of Ag NPs between TiO 2 thin-film (TF) and NW. The average length of the vertical TiO 2 NW and diameter of Ag NPs (with density ~10 12 cm 2 ) were found to be ~ 350 nm ±5 nm and ~3.2 nm ± 0.4 nm, respectively. An enhanced photoluminescence was observed in case of Ag NPs capped TiO 2 NWs due to the presence of high carriers as compared to bare TiO 2 NW. The capacitance (C) -voltage (V) hysteresis was measured for both Ag NPs capped TiO 2 NW and bare TiO 2 NW at different sweeping voltage (±3V to ±10 V) at 1 MHz frequency. A high capacitive memory window of 7.12 V was obtained for Ag NP capped TiO 2 NW at ±10 V with an excellent endurance upto 1000 cycle. Significantly lesser charge loss of 23% was obtained after a span of 10 4 s with a hole and electron loss of 10.6% and 17.8% respectively. The program and erase process in the device was explained with the help of a band diagram.

“…Mondal et. al., also reported that Ag decorated TiO 2 TF enhanced the capacitive memory as compare to bare TiO 2 TF [14] . Similarly, enhanced memory window using metal NPs decorated high-k dielectric based capacitive memory was also reported [15] [16] but all of the above memory needs a significant improvement.…”

Over the past decade, metal nanoparticles (MNPs) have attracted extensive attention due to their unique physiochemical properties that make them highly applicable in various fields such as chemical sensing, energy storage, catalysis, medicine, and environmental engineering. Their physiochemical properties depend drastically on the MNP size and morphology, which are largely determined by their synthesis methods. Research on MNPs predominantly focused on coinage metals (Au, Ag and Cu), but in the last decade research on metals with a relatively high melting temperature such as Pd, Co, and Re has seen rapid increases, mainly driven by their potential applications as catalysts. This paper presents the recent advances on different synthesis techniques of Co, Pd, and Re nanoparticles, their resulting nanostructures, as well as existing and potential applications.
