A Molecular-Rotor Device for Nonvolatile High-Density Memory Applications

High density Ru nanocrystal deposition for nonvolatile memory applications

Arrays of Ru nanocrystals 1–4 nm in diameter are deposited via a hybrid chemical vapor deposition/atomic layer deposition reaction. The nanocrystal density is found to depend sensitively on the nucleating surface. A maximum density of 7–8 1012 cm−2 is achieved on Al2O3. Incorporation of these nanocrystals in floating-gate memory cells results in C-V curves that exhibit large, counterclockwise h...

Nonvolatile read-out molecular memory.

A versatile molecule is described that performs as a nondestructible read-out optical-storage molecular memory. This molecular memory is composed of two distinct molecules that are chemically bonded to each other to form a single molecule with unique properties. One component is a photochromic fulgimide, and the other is a strongly fluorescing oxazine dye. This composite molecule was specifical...

High-density NiSi nanocrystals embedded in Al2O3/SiO2 double-barrier for robust retention of nonvolatile memory

NiSi nanocrystals of high density and good uniformity were synthesized by vapor–solid–solid growth in a gas source molecular beam epitaxy system using Si2H6 as Si precursor and Ni as catalyst. A metal– oxide–semiconductor memory device with NiSi nanocrystal–Al2O3/SiO2 double-barrier structure was fabricated. Large memory window and excellent retention at both room temperature and high temperatu...

Graphene oxide thin films for flexible nonvolatile memory applications.

There has been strong demand for novel nonvolatile memory technology for low-cost, large-area, and low-power flexible electronics applications. Resistive memories based on metal oxide thin films have been extensively studied for application as next-generation nonvolatile memory devices. However, although the metal oxide based resistive memories have several advantages, such as good scalability,...
