Controlled one-dimensional nanostructures in poly(3-hexylthiophene) thin film for high-performance organic field-effect transistors

Article Abstract:

The nanostructures of poly(3-hexylthiophene) (P3HT) thin film are controlled by changing the solvent vapor pressure in a spin-coating chamber during solidification in order to improve the field-effect mobilities in P3HT thin film transistors. The relatively high field-effect mobilities are attributed to the higher solvent vapor pressure during film formation, providing the solvent is allowed to evaporate slowly and the degree of ordering within the P3HT crystalline domains is dramatically improved.

Combined effect of chain length and phase state on adhesion/friction behavior of self-assembled monolayers

Article Abstract:

The combined effects of phase state and chain length on the adhesion and friction behavior of self-assembled monolayers (SAMs) are demonstrated using atomic force microscopy (AFM). The study reveals the chain effect on adhesion/friction can be correctly evaluated by examining the phase-state dependence of adhesion/friction behind the chain length effect.

Study of the morphological and adhesion properties of collagen fibers in the Bruch's membrane

Article Abstract:

Atomic force microscopy is used to examine the morphological and adhesion properties of collagen fibers located in different portions of the membrane. The adhesion properties of the collagen fibers were evaluated using force volume imaging on a number of different eye samples.
