Outer space grown semi-insulating GaAs and its applications

Science China(Technological Sciences) 1999年第5期42卷 456-461页

作者：林兰英张绵钟兴儒陈诺夫 masayoshi yamada Laboratory of Semiconductor Materials Science Institute of Semiconductors Chinese Academy of Sciences Hebei Institute of Semiconductors Department of Electronics & Information Science Kyoto Institute of Technology

GaAs single crystal has been grown in recoverable satellite. Hall measurements indicate that the GaAs shows semi-insulating behavior. The structural properties of the crystal have been improved obviously, and their uniformity has been improved as well. The stoichiometry and its distribution in space-grown GaAs are improved greatly compared with the GaAs single crystal grown terrestrially. The properties of integrated circuits made by direct ion-implantation on space-grown GaAs are better than those made on ground-grown materials. These results show that the stoichiometry in semi-insulating GaAs seriously affects the properties of related devices.

Successful endoscopic closure of a colonic perforation one day after endoscopic mucosal resection of a lesion in the transverse colon

A 73-year-old man underwent endoscopic mucosal resection(EMR) of a 20-mm flat elevated lesion on the transverse colon. The morning after the procedure, he started to have severe right upper quadrant pain after his first meal. A computed tomography scan revealed free air and a stomach filled with food. He was diagnosed to have delayed post-EMR intestinal perforation. He underwent emergent colonoscopy and clipping of the perforated site. He was discharged 8 d after the endoscopic closure without the need for surgical intervention. The meal was not the cause of the colon transversum perforation.
