Researchers Twister chase elusive storm data
2017/10/24
Some great ideas are born out of years of painstaking research. Others are gleaned from the plotline of the movie "Twister."The latter is how Paul Markowski, professor of meteorology, and Yvette Richa...
Tips-Pentacene OTFT电极接触电阻的研究
转移线性法 有机薄膜晶体管 接触电阻 喷墨打印
2014/3/20
采用转移线性法分析了以PVP为栅绝缘层、以Tips-pentacene为有源层的有机薄膜晶体管(OTFT)电极与有源层间的接触电阻,其中介电层和有源层均采用旋涂法制备,银电极采用喷墨印刷法制备。沟道长度分别取200,250,300 μm和400 μm,有源层退火时间分别为2 h,6 h和10 h,提取到的3种不同退火时间的OTFT的接触电阻分别为8 MΩ,4.5 MΩ和3 MΩ,退火10 h的OT...
Strong-field above-threshold photoemission from sharp metal tips
Strong-field above-threshold photoemission sharp metal tips
2010/10/20
We present energy-resolved measurements of electron emission from sharp metal tips driven with
low energy pulses from a few-cycle laser oscillator. We observe above-threshold photoemission with a pho...
Some Ultrastructural Observations on Calcium Oxalate Raphide Crystal Idioblasts and Meristematic Cells of the Adventive Root Tips of Sternbergia lutea (L.) Ker-Gawl. ex Sprengel (Amaryllidaceae)
Sternbergia lutea adventive root tip meristematic cell Ca-oxalate raphide crystal idioblast degeneration ultrastructure
2010/3/23
The adventive root tip cells of a bulbous plant, Sternbergia lutea (L.) Ker-Gawl. ex Sprengel (Amaryllidaceae), were examined by LM (light microscope) and EM (electron microscope). At the meristematic...
