#372 Carbon is still semiconductor of the future

Speaking of elemental semiconductors (see previous blog), in contrast to silicon, carbon  in the form of diamond is having problems getting into the mainstream semiconductor technology. This is in spite of its in many ways superior to silicon physical characteristics such as width of the energy gap, thermal conductivity, and others,. But, unfortunately, one shortcoming related to the n-type doping challenges (click here for an expert assessment of diamond electronics). 


Things may change for the better because unlike no other solid element, carbon can be obtained and explored in all geometrical configuration including  3D diamond, 2D graphene, 1D carbon nanotubes, and 0D carbon quantum dots. Between these four configurations carbon displays a number of very attractive characteristics. So, if not diamond, them may be nanototubes or graphene. Or may  be quantum dots….


For now however, carbon still is a semiconductor of the future.
