Accurate conversion of wideband multi-GHz analog signals into the digital domain has long been a target of analog-to-digital converter (ADC) developers, driven by applications in radar systems, software radio, medical imaging, and communication systems. Aperture jitter has been a major bottleneck on the way towards higher speeds and better accuracy.(More)
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)
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)
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)
Single-walled carbon nanotube (SWNT) is a rolled up graphene. They exhibit unique properties due to their one-dimensionality, and their properties depend on their structure. Although structure control is important for many applications of SWNTs, it is still difficult to control it in their growth stage. In this paper, we showed the diameter and direction(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)
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)
