The relationship of the magnitude of the contact angles between the melts and the substrates was as follows: the angles of pBN, BN, and graphite were the largest, and those of others were in the order of AlN, SiN, SiO2, and Al2O3. The angles of SiC were almost the same as Al(2)O3. The surface tension of In(0.8)Ga(0.2)As was gamma = 418 to 480 mN/m (at 1,100 to 1,300 C). The effect of roughness of the SiO2 container was investigated from 0.1 to 4 micrometer amplitude of surface. As a result, the molten InGaAs/container wetting behavior was related to the roughness of the container., 資料番号: AA0002208004, レポート番号: NASDA-TMR-990006E}, title = {Wettability and surface tension of molten InGaAs}, year = {1999} }
