	InGaAs nanoflowers grown by MOCVD (EI CONFERENCE) 会议论文 OAI收割 2012 Spring International Conference on Material Sciences and Technology, MST-S, May 27, 2012 - May 30, 2012, Xi'an, China 作者: Zhang T. 收藏 \| 浏览/下载：23/0 \| 提交时间：2013/03/25 InGaAs nanoflowers have been prepared on InP substrates by MOCVD using TMIn TMGa and AsH3 as reactive precursors at 420 C. Through observation by scanning electron microscopy we find that InGaAs nanoflowers are composed with blades and rods. The flower patterns are controlled by the growth temperature. The nanoflowers of InGaAs are disappeared when we alter the growth temperature up and down. The InGaAs nanoflowers are In0.98Ga0.02As. (2012) Trans Tech Publications Switzerland.

	The synthesis and field emission property of carbon nanotubes on carbon fibers substrate (EI CONFERENCE) 会议论文 OAI收割 Technical Digest of the 20th International Vacuum Nanoelectronics Conference, IVNC 07, July 8, 2008 - July 12, 2008, Chicago, IL, United states Leyong Z.; Weibiao W.; Jingqiu L.; Yuxue X.; Da L.; Song C.; Haifeng Z. 收藏 \| 浏览/下载：33/0 \| 提交时间：2013/03/25 Using ferrocene as catalyst precursor C2H2 as carbon source carbon nanotubes (CNTs) with uniform density were synthesized on carbon fibers substrate by floating catalyst method. The morphology and microstructure were characterized by field emission scanning electron microscope (FESEM) and high-resolution transmission electron microscopy (HRTEM). The observation showed that the length of CNTs is about 2 m the average space between adjacent CNTs is about 300 nm and the diameter of CNT is about 45 nm. The less dense "short and stubby" aligned CNTs films should have good electron field emission characteristics. The results of field emission showed that the emission current of CNTs/carbon fibers was 5 A at the field of 2.5 V/m and the emission current can be 280 A with a field of 7 V/m (the specimen area is 0.25 cm2 and the distance between cathode and anode is 200 m). The calculation based on the F-N plot indicated that the field enhancement factor of CNTs tip is 499122. Using the conductivity and chemical stability of carbon fibers and the uniform and sparse density distribution of CNTs on carbon fibers substrate the tip predominance of carbon nanotubes can be exerted and simultaneously the effect of screening effects between adjacent carbon nanotubes on the field emission performance can also be effectively decreased. The CNTs synthesized on carbon fibers substrate has many predominances for the fabrication of cold cathode devices. For example using the removability of carbon fibers the cathode of CNTs/carbon fibers can be arbitrarily moved enlaced or combined to form different patterns and the cathode of CNTs/carbon fibers can be also fabricated in large size. Therefore CNTs/carbon fibers may have potential application in field emission displays.
