Electrical Breakdown of Aliphatic and Aromatic Self-Assembled Monolayers Used as Nanometer-Thick Organic Dielectrics

Solution-deposited organic-inorganic hybrid multilayer gate dielectrics. Design, synthesis, microstructures, and electrical properties with thin-film transistors.

We report here on the rational synthesis, processing, and dielectric properties of novel layer-by-layer organic/inorganic hybrid multilayer dielectric films enabled by polarizable π-electron phosphonic acid building blocks and ultrathin ZrO(2) layers. These new zirconia-based self-assembled nanodielectric (Zr-SAND) films (5-12 nm thick) are readily fabricated via solution processes under ambien...

Conductive Scanning Force Microscopy on Linear-chain Organic Films

The electrical properties of self-assembled monolayers (SAMs) of organic molecules on metal surfaces have gained particular interest due to their potential applications in nanometer-scaled electronics systems [1]. Understanding the transport mechanism through these thin molecular films as well as the dependence of the conductivity on the molecular length and structure, the applied load and the ...

Study on the barrier properties and interfacial properties of self-assembled monolayers (SAMs) of aliphatic, aromatic and alkoxycyanobiphenyl thiols on gold surface prepared using a lyotropic liquid crystalline phase as an adsorbing medium

Study of the packing density and molecular orientation of bimolecular self-assembled monolayers of aromatic and aliphatic organosilanes on silica.

Bimolecular self-assembled monolayers (SAMs) of aromatic and aliphatic chlorosilanes were self-assembled onto silica, and their characteristics were established by contact angle measurement, near-edge X-ray absorption fine structure spectroscopy, and Fourier transform infrared spectroscopy. Three aromatic constituents (phenyltrichlorosilane, benzyltrichlorosilane, and phenethyltrichlorosilane) ...

Self-assembling organic thin-film transistors

Organic thin-film transistor (OTFT) dielectric layers that selfassemble and enable transistor function at low voltages have been developed by a team of chemists. Myung-Han Yoon et al. developed working transistors that employ organosilane-based dielectric layers that organize themselves from solution. The resulting dielectric films are 2.3–5.5 nm thick, smooth, and nearly defect-free. The films...
