We report the suspension of individual multi-walled carbon nanotubes (MWNTs) from the bottom substrate using deep trench electrodes that were fabricated using optical lithography. During drying of the solution in dielectrophoretic assembly, the capillary force pulls the MWNT toward the bottom substrate, and it then remains as a deformed structure adhering to the bottom substrate after the solution has dried out. Small-diameter MWNTs cannot be suspended using thin electrodes with large gaps, but large-diameter MWNTs can be suspended using thicker electrodes. We present the statistical experimental results for successful suspension, as well as the feasible conditions for a MWNT suspension based on a theoretical approach.

자연계에 존재하는 다양한 생명체 중 몇몇은 벽이나 천장을 자유자재로 걸어다니거나 뛰어다닌다. 이러한 생명체 중 대표적으로 Tokay Gecko는 그 발가락 표피에 수십억개의 주걱모양의 나노헤어를 가지고 있으며, 이러한 나노헤어는 부착하고자 하는 표면과의 원자수준의 끌어당기는 힘을 발생시키게 되며 이 힘을 이용해 접착제 없이 부착력을 얻게 되는 것이다. 최근 $7{\sim}8$년 동안 많은 연구자들은 이를 모방한 건식부착물의 제작 연구를 수행하고 있으며, 본 논문에서는 이러한 연구들의 개관을 통해 향후 연구방향에 대해 논의하고자 한다.

Experimental investigations are carried out for the characteristics of bubble rise in the Miniature Two-Phase closed Thermosyphon(MTPCT) with a thin wire insert. The working fluids applied as experimental media are of three kinds: water, methanol, and ethanol. The effects of combination of the inclination with diametric ratio $\alpha$(=d$_{0}$/D$_{I}$) on rising velocity of a large bubble in the thermosyphon are explicitly analyzed. The realm of a movable bubble and the critical value of $\alpha$ are iteratively pursued to interpret the region Figures-of-Break, rooted in the governing physics relations, according to the application of working fluid. Experimental results are compared with those of analysis and critical ranges for $\alpha$ and D$_{I}$ were ascertained from comparisons.isons.
