#275 Carbon is future

Among elements in group IV of the periodic table displaying strong semiconductor properties, which include carbon (C), silicon (Si), and germanium ( Ge), silicon continues to be a dominant force since the time it dethroned germanium some 50 years ago. Although this status quo is not expected to change for many years to come, I would like to point out to somewhat unexpected (yes, unexpected… did you hear about graphene some 10-12 years ago?) emergence of carbon as a problem-solving electronic material of the future.

With several allotropes, including graphite, diamond and amorphous phase, carbon covers unusually broad and highly diverse, for a single element, range of physical properties.  In electronics, graphene, nanotubes and diamond are the forms of carbon generating tremendous excitment regarding their possible application. Recently demonstrated form of carbon in between graphene and diamond, and known as diamane, which is a result of several layers of graphene collapsing under certain conditions into diamond matrix, also stirs imagination of device engineers and at the same time further demonstrate an immense potential of cabon. As all of this wouldnot be enough, carbon is also a component of silicon carbide (SiC) which has established itself as a key player in power device technology.

Well, I may not know exactly when, but I know that the era of carbon in semiconductor device engineering will descent upon us....
