The electro-optic properties of 1.3 mm self-assembled InAs=GaAs quantum dots grown by metal organic chemical vapour deposition are reported. The linear and quadratic electro-optic coefficients are 2.4 10 11 m=V and 3.2 10 18 m=V, respectively, which are significantly larger than those of GaAs bulk materials. Also, the linear electro-optic coefficient is almost comparable to that of lithium niob...

A black mask (BM) is a layer used to improve the display quality by suppressing light leakage. In general, the BM is formed by a photolithography process. In this study, a novel technique for the fabrication of a quasi-black mask (q-BM) is proposed; the q-BM was composed of vertical and hybrid orientation areas, patterned by a separation coating technique using an electro-spray deposition metho...

Electro less deposition is an autocatalytic chemical technique to deposit a coating of metal on a work piece with the presence of a reducing agent. Electro less nickel coating has high advantages in electroplating. In this work the changing structure of nickel deposits on aluminum and its alloys at the early stage of electro less nickel deposition using sodium hypophosphite ion used as reducing...

The carbon based coils with the nanometer scale have the 3 dimension helix geometry. We synthesized the carbon nano-coils by the use of chemical vapor deposition technique with iron and tin as the catalysts. The fabricated coils have the external diameter of ranging few hundred nm to few thousand nm. The Scanning Electro-Microscope (SEM) and Tunneling Electro-Microscope has shown detail images ...
