Answer 1

If microchips are made from diamond wafers then computers will generate less heat. There are many other advantages of diamond wafers over Si or Ge wafers:-

Diamond can run 5 times hotter than Silicon without degrading in performance and is more easily cooled (with 22 times the heat transfer efficiency of silicon), can tolerate higher voltages before breaking down, and electrons (and electron-holes) can move faster through them. Already, semiconductor devices with diamond material are available that deliver one million times more electrical current than silicon or previous attempts using diamond.

Diamond-based semiconductors are capable of increasing power density as well as create faster, lighter, and simpler devices
