Recent progress in gold nanoparticle-based non-volatile memory devices

Abstract

Recently, much progress has been made toward the fabrication of non-volatile memory devices based on metallic nanoparticles. Among the many kinds of nanoparticles, gold nanoparticles are some of the most widely used materials for charge trapping elements in non-volatile memory devices because they are chemically stable, easily synthesized, and have a high work function. Various synthesis methods have been applied to fabricate gold nanoparticle-based nonvolatile memory devices and recent progress indicates that gold is a very promising material for non-volatile memory applications. In this article, the recent advances in fabrication and characterization of gold nanoparticle-based nonvolatile memory devices, with an emphasis on flash memory-type memory devices, are reviewed. Detailed device fabrication, characterization, and future directions are reported based on the recent research activities and literature.

Plant-Extract-Assisted Green Synthesis of Silver Nanoparticles Using Origanum vulgare L. Extract and Their Microbicidal Activities

“…Amongst various nanoparticles, AgNPs have received particular attention due to their unique morphologies, stability, and controlled geometry [2]. AgNPs have been largely used in various electronic and sensing devices, coating materials, data packing, and molecular switches [3][4][5]. Apart from this, they have also been applied in the diagnosis and treatments of various diseases [6].…”

Oxygen-free precursor for chemical vapor deposition of gold films: thermal properties and decomposition mechanism

“…3 because the molecular ions of ethane and n-butane have low intensities and their mass spectra in the range of the fragmentary ions are superimposed on the mass spectra of other molecular species. 2 Notice that β-hydride elimination is an event of low probability because no signals corresponding in particular to methane have been recorded. Thus, the reductive coupling of alkyl fragments to give ethane, propane, and butane seems to be more probable.…”

“…Gold thin films and nanostructures have numerous valuable applications in microelectronic devices [1][2][3][4], optical devices [5,6], catalysis [7,8], etc. To manufacture goldcontaining films, chemical vapor deposition (CVD) is a promising method allowing preparation of conformal coatings on different types of substrates with effective control of morphology of the forming films [9][10][11][12][13].…”

Three-dimensional structure of Au nanoparticles supported on amorphous silica and carbon substrates

“…Gold nanoparticles in the size regime of a few nanometers, supported on insulating oxides, have attracted much research efforts recently due to a variety of applications such as nanoelectronics and catalysis [1,2]. Silica (SiO 2 ) is one of such supports [3].…”
