We used both R-cut and R-face crystal quartz substrates for the growth of horizontally aligned single-walled carbon nanotubes (SWNTs). The R-plane (10–11) is one of the low-index crystallographic planes of crystal quartz. The surface cut from a synthetic quartz block parallel to the R-plane was used as R-cut substrates, and the exposed R-plane was used as(More)
In this study, we investigated carbon feedstock decomposition conditions on the synthesis of single-walled carbon nanotubes (SWNTs) by chemical vapour deposition. We simulated gas-phase thermal decomposition of ethanol and dimethyl ether (DME) at typical SWNT growth conditions using the chemical kinetic model, and confirmed the reaction trends and primary(More)
We investigated the thermal and electrical conductivity of water seeded with single-walled carbon nanotubes (SWCNT) synthesized using the alcohol catalytic chemical vapour deposition method. Sodium deoxycholate was used as the surfactant to prepare stable nanofluids, which we then thoroughly characterized by microscopic and spectroscopic methods. Electrical(More)
An organic film-assisted electrical breakdown technique is proposed to selectively remove metallic (m-) single-walled carbon nanotubes (SWNTs) in full length towards creation of pure semiconducting SWNT arrays which are available for the large-scale fabrication of field effect transistors (FETs). The electrical breakdown of horizontally aligned SWNT arrays(More)
Tall birch trees allocate extra resource due to aboveground temperature elevation to bud and male flower production rather than to plant growth. Saplings increased only plant growth under warming. Size-dependent response should be considered. We experimentally heated canopy organs of tall birch trees (Betula ermanii Cham.; 18–20 m high) growing at a high(More)
Horizontally aligned single-walled carbon nanotubes (SWNTs) grown on crystal quartz substrate are very promising material for electronics devices such as field-effect transistors (FETs). In addition to the CVD growth control [1,2] and characterization of chirality distribution of aligned SWNTs, we will discuss two manipulation techniques of horizontally(More)
In this paper we present the piezoelectric-driven deformable micro-mirror for optical wavefront correction. The mirror membrane was fabricated on diaphragm structure composed of piezoelectric PZT thin films on Si substrate. The application of voltage induced large deflection of the surface of the diaphragm
We studied the influence of gas pressure on the growth of horizontally aligned single-walled carbon nanotubes (SWCNTs) on R-cut crystal quartz substrates by alcohol chemical vapor deposition. The density of horizontally aligned SWCNTs was found to depend highly on gas pressure. Time evolution of horizontally aligned SWCNT growth revealed that the density of(More)
Controlling the detailed structures of single-walled carbon nanotubes (SWNTs) is imperative for realizing many SWNT applications, and understanding the SWNT growth mechanism is important to improve the growth techniques. In the present study, we performed SWNT growth by a catalytic chemical vapor deposition (CVD) method in wide temperature and pressure(More)
