Three Dimensionally Oriented Polyacetylene

Stress in three-dimensionally integrated sensor systems

Three-dimensionally slanted illusory contours capture stereopsis

In stereo capture a stereogram of a crossed illusory figure pulls a texture bounded by the illusory contours to the same depth plane with the illusory figure. We investigated whether three-dimensionally curved and slanted illusory figures could capture a repeating background texture. According to results, stereoscopic capture was perceived when a disparate illusory contour was slanted provided ...

Three-dimensionally Confined Diluted Magnetic Semiconductor Clusters

We report the first example of a dilute magnetic semiconductor (DMS) confined in all three dimensions (DMS quantum dot). Zn0.93Mn0.07S clusters o f 2 5 A diameter are successfully synthesized inside a glass matrix and fully characterized by chemical analysis, x-ray diffraction, extended x-ray absorption fine structure (EXAFS), and photoluminescence spectroscopy. Effect of size quantization on t...

Three-dimensional structure and intrinsic defects in trans-polyacetylene.

We report first-principles local-density-functional pseudopotential calculations of static and dynamic electronic structure properties of crystalline 3D trans (CH-) " We .find a broken-symmetry ground state of P21/a symmetry with in-phase dimerizations. Using a Green's-function technique, we show that the 3D character of the electronic band-edge states strongly suppresses self-trapping, destabi...

DNA as functional material with one-dimensionally oriented molecular chains

Materials with the structures in nanometer scale have emerging importance in the technology. In the present article, the development in molecular chain alignment of DNA was reviewed, including our recent new technologies to fabricate molecular chain-oriented DNA films. It was found that two different mechanisms play essential roles in the orientation of DNA molecular chains. One is the alignmen...
