an Al2O3/a-Si stack depositing on TCO has been proposed [26]. The a-Si layer is applied as absorber to thelaser irradiation, which regions the Al2O3film are ablated and the plating openings on TCO are created. However, deposition of Al2O3/a-Si stack layers need two additional vac...
Assuming an average copper concentration of 0.4% in stamp sands (Kerfoot et al., 2002), the amount of anthropogenic copper released along the entire Keweenaw coastline was approximately 256 × 103 metric tonnes, about 2.4 times greater than the entire anthropogenic sediment burden (ca. 108 × ...
