Even so, This is when they begin diverging. Silicon is much lighter which has a density of 2.33g/cm3, making it ideal for excess weight-delicate programs and less than 50 percent the density of germanium. In addition, it is a lot more thermally resistant than germanium and that has a Knoop Hardness of 1150 Additionally it is harder and fewer brittle. Silicon also expenses fewer which makes it a better applicant in several apps.
