Improving strength and rollability of alloys, transistors and semiconductors. 2. Using germanium instead of silicon as transistor material would enable faster chips containing smaller transistors because higher switching speeds than in silicon could be achieved using germanium. Packaging Vacuum package, 10G, 50G,100G,500G per bags or as needed.   If you have a question about pricing , need a quote, would like to inquire about whether Germanium Metal Powder (Ge) is in stock, or require any other assistance in placing an order, please e-mail us at hwnano@xuzhounano.com or call  at 86-20-87748917  87226359. thank you.
