Gallium arsenide did not alter the phagocytic ability of macrophages. Peritoneal macrophages normally processed the targeted antigen, indicating that gallium arsenide influenced compartment(s) preceding lysosomes. However, the processing efficiency of exposed splenic macrophages depended on the size of particulate cytochrome, suggesting that processing varied in phagolysosomes of different ...

Epitaxial lift-off process for gallium arsenide substrate ...

Epitaxial lift-off process enables the separation of III-V device layers from gallium arsenide substrates and has been extensively explored to avoid the high cost of III-V devices by reusing the substrates. Conventional epitaxial lift-off processes require several post-processing steps to restore the substrate to an epi-ready condition. Here we present an epitaxial lift-off scheme that ...

GaAs Reclaim What Is the Reclaiming Process?

27/02/2017  As technology continues to advance, Gallium Arsenide (GaAs) wafer usage continues to rise. GaAs wafers are extremely appealing to technological applications for numerous reasons. However, one of the biggest factors for GaAs wafer usage is that GaAs move electrons faster than silicon while consuming less power. Despite it’s benefits, or perhaps because of them, GaAs wafers can be rather
