Initially considered a waste product in mining, it was identified as a semimetal by the Swedish chemist and metallurgist Georg Brandt in the 1730s.
I did my diploma work under Prof.G. Busch on the Hall effect of grey tin, now known as a semimetal, and, prompted by his fine lectures, also became acquainted with modern solid-state physics.
Graphene has significant potential for application in electronics but cannot be used for effective field-effect transistors operating at room temperature because it is a semimetal with a zero bandgap.
Especially in cases of high value or trees that are either semimetal in nature or hard to replace the results can be catastrophic and either hard to replace, very expensive to replace or both.
Graphene, or single-layered graphite, with its high crystallinity and interesting semimetal electronic properties, has emerged as an exciting two-dimensional material showing great promise for the fabrication of nanoscale devices.
