FIB와 나노메니퓰레이터를 이용한 다양한 nano manufacturing을 통해 단일 나노선 소자제작 및 평가가 가능하였으며 또한 나노물질 자체의 전기적, 기계적 특성 평가를 수행할 수 있었다. 나노메니퓰레이터를 나노선에 직접 접촉시켜 전기적 특성을 평가하는 기술은 STA 등과 함께 사용될 때 높은 신뢰도를 갖는 신호를 얻을 수 있었다. 특히, 이를 이용한 나노 소재 특성 평가기술은 소자제작 시간을 단축시킬 수 있고 패턴닝으로부터 화학적 오염을 줄일

Nanopowders of titanium dioxide incorporating the transition metal element(s) were synthesized by flame synthesis method. Single element among Fe(III), Cr(III), and Zn(II) was doped into the interior of crystal; bimetal doping of Fe and Zn was also made. The characteristics of transition-metal-doped nanopowders in the particle feature, crystallography and electronic structures were determined with various analytical tools. The chemical bond of Fe-O-Zn was confirmed to exist in the bimetal-doped nanopowders incorporating Fe-Zn. The transition element incorporated in the was attributed to affect both Ti 3d orbital and O 2p orbital by NEXAFS measurement. The bimetal-doped nanopowder showed light absorption over more wide wavelength range than the single-doped nanopowders

ZnO nanostructures with various shapes were synthesized under ambient pressure condition by a wet chemical reaction method. Nanorods of ZnO with hexagonal cross-section and their aggregates with radiate shape were synthesized. Precursor concentration affected considerably the shape evolution of ZnO nanorods. Low precursor concentration was proved to be more preferable to the growth of ZnO nanorods, which is attributed to the intrinsic characteristics of chemical reaction in the synthesis of ZnO from zinc compounds.

Nanostructured and composite powders have been prepared by mechanochemical reaction from mixtures of Ti, BN, and powders. The raw materials have reacted to form a uniform mixture of TiN, and or depending on the amount of used in the starting mixtures, and the reaction proceeded through so-called mechanically activated self-sustaining reaction (MSR). Fine TiN and crystallites less than a few tens of nanometer were homogeneously dispersed in the amorphous or matrix after milling for 12 hours. These amorphous matrices became crystalline phases after annealing at high temperatures as expected, but the original microstructure did not change significantly

We report a carbothermal reduction process for massive synthesis of monolithic WO phase from tungsten oxide in the presence of carbon source. Carbon black powder was used as a carbon source and added to WO by 40 weight percent. Bundles of WO rods were formed over the temperature range of 80 to 90. Pure WO bundles could be separated from the mixture of WO and residual carbon black powder. Field emission character of WO phase was determined using the extracted WO rods. Flat lamp fabricated from the WO rods showed the turn-on field of 9.3 V/
