Symmetry selected quantum dynamics of few electrons in nanopillar transistors.

Study on single electron tunnel using current-voltage characteristics in nanopillar transistors at 298 K show that the mapping between the N electron excited in the central box ∼8.5 × 8.5 × 3 nm and the N tunnel peak is not in the one-to-one correspondence to suggest that the total number N of electrons is not the best quantum number for characterizing the quality of single electron tunnel in a three-dimensional quantum box transistor.

The temperature-dependent physical and electrical characteristics of a polymer/RAFT-polymer stabilized nanoparticle system for organic nonvolatile memory.

We have fabricated and investigated organic memory diodes, comprising a single polymer layer and Au nanoparticles stabilized by the same polymer material utilizing a reversible addition-fragmentation transfer technique to suppress phase separation. The organic memory diodes exhibit well reproducible and prominent current bistability and good charge retention characteristics free from phase separation issues. Nondestructive spectroscopic ellipsometry is used to characterize the physical properties of the polymer/nanoparticle composites, such as the polymer's effective dielectric function/layer thickness and the Au nanoparticle's effective volume fraction, which are important parameters for gaining insightful information on charge transport in this system.
