Deposition of Silver Nanoparticles on Indium Tin Oxide Substrates by Plasma-Assisted Hot-Filament Evaporation
Nanoparticles of noble metals have unique properties including large surface energies, surface plasmon excitation, quantum confinement effect, and high electron accumulation. Among these nanoparticles, silver (Ag) nanoparticles have strong responses in visible light region due to its high plasmon excitation. These unique properties depend on the size, shape, interparticle separation and surrounded medium of Ag nanoparticles. Indium tin oxide (ITO) is widely used as an electrode for flat panel devices in such as electronic, optoelectronic and sensing applications. Nowadays, Ag nanoparticles were deposited on ITO to improve their optical and electrical properties. Plasma-assisted hot-filament evaporation (PAHFE) technique produced high-density of crystalline Ag nanoparticles with controlling in the size and distribution on ITO surface. In this chapter, we will discuss about the PAHFE technique for the deposition of Ag nanoparticles on ITO and influences of the experimental parameters on the physical and optical properties, and electronic structure of the deposited Ag nanoparticles on ITO.

Perovskites in Next Generation Memory Devices
Although perovskites are widely employed in other industries such as photovoltaics and light-emitting diodes (LEDs), digital technology is rapidly gaining pace in today’s market and shows no signs of abating. As a result, the progress of system memory and memory storage has accelerated into new inventions. The invention of dynamic Random-Access Memory (RAM) in the 1960s laid the groundwork for today’s multibillion-dollar memory technology sector. Resistive switching (RS) capabilities of perovskite-based materials such as perovskite oxides and metal halides have been extensively studied. Chemical stability, high endurance, quick writing speed, and strong electronic interaction correlation are some of the benefits of employing perovskites in RS devices. This chapter will investigate the progress of system memory and memory storage employing perovskites, the advantageous properties of perovskites utilized in memory devices, the various types of RS employing perovskites, as well as the research challenges that perovskite-based memory systems face in future commercial development.
