Fig. 2From: Fabrication of SrGe2 thin films on Ge (100), (110), and (111) substratesSEM images of the samples after the Sr deposition. The crystal orientation of the Ge substrate is a−e (100), f−j, (110), and k−o (111). Tsub is ranged from 300 to 700 °C for each substrate. The arrows in each image show the crystal directions of the Ge substratesBack to article page
