应变异质结外延材料的缓冲层厚度与Frank-Read源的关系研究

基于能量最小近似模型,研究了应变异质结外延材料中,产生Frank-Read源以释放失配应力所需GeSi合金缓冲层的厚度。对Ge_xSi_(1-x)/Si进行了具体计算,其结果表明:产生Frank-Read源时缓冲层厚度要比临界厚度大得多,L_(min)=1300A是钉扎点间的最小距离。计算结果与LeGoues等的实验结果相符。就作者所知,计算产生Frank-Read源时GeSi合金缓冲层厚度的工作,以前未见报道。

Rediscovery of the sea cucumber "Toxodora" pacifica Ohshima, 1915 (Echinodermata : Holothuroidea : Apodida)

The apodous holothurian species originally described by Ohshima ( 1915) as Toxodora pacifica has been rediscovered, and its known geographic range extended from Suruga Bay, Japan to the western side of the Yellow Sea, China. As the genus name Toxodora is no longer available, a new genus name, Neotoxodora Liao, Pawson, and Wei, is proposed. The type material of Neotoxodora pacifica is lost, and a Neotype is named for this species.
