Source: The main ore of germanium is germanite, which is about seven% germanium. Commercially, germanium is received like a byproduct of steel refining and from some coal ashes.Nghiên c?u c?a FDA ??a ra k?t lu?n r?ng germani, khi s? ??ng nh? là ch?t b? sung dinh d??ng, "th? hi?n m?t s? nguy hi?m ti?m tàng cho s?c kh?e con ng??i".[6]5 categories

Germanium is mainly a byproduct of zinc ore processing.  This is a challenging, grayish-white element; it's a metallic luster and the identical crystal composition as diamond; and it really is brittle, like glass.  Furthermore, it is important to notice that germanium is a semiconductor, with electrical properties among Those people of a metal

After that, electrical properties in the Make contact with are talked about. The position of germanium crystal orientation in ohmic and Schottky properties of your Make contact with is analyzed. Fermi amount pinning (FLP) performs a role mostly on metal/(one hundred) n-type Ge interfaces. The function of FLP is minimum on p-type Ge and also other c
