Modeling of retention characteristics for metal and semiconductor nanocrystal memories

The charge retention characteristics of metal nanocrystal (MNC) and semiconductor nanocrystal (SNC) memory devices are comparatively studied in this paper. A charge retention model is proposed, taking into account the quantum confinement effect, to account for the better retention characteristics of metal nanocrystal memory observed in the experiment. Simulation results are in good agreement wi...

Molecular rectification in metal-SAM-metal oxide-metal junctions.

This Article compares the ability of self-assembled monolayers (SAMs) of alkanethiolates with ferrocene (Fc) head groups (SC(11)Fc), and SAMs of alkanethiolates lacking the Fc moiety (SC(10)CH(3) and SC(14)CH(3)), to conduct charge. Ultraflat surfaces of template-stripped silver (Ag(TS)) supported these SAMs, and a eutectic alloy of gallium and indium (EGaIn), covered with a skin of gallium oxi...

Advocating Noise as an Agent for Ultra-Low Energy Computing: Probabilistic Complementary Metal--Oxide--Semiconductor Devices and Their Characteristics

Noise immunity and low-energy computing have become limiting factors in the semiconductor roadmap as transistor feature sizes shrink. The subject of our study is the probabilistic switch, implemented in the complementary metal–oxide– semiconductor (CMOS) domain, referred to as a probabilistic CMOS (PCMOS) switch, whose behavior is rendered probabilistic by noise. In conducting this study, we ar...
