WebNov 1, 2024 · Graphene sheets are also used as biosensors and can help diagnose cancer and neurological diseases (e.g. epilepsy or Parkinson’s disease) with portable devices. The graphene probe developed by the Poles is expected to revolutionize ECG testing by allowing measurements from the heart level. Graphene is a zero-gap semiconductor, because its conduction and valence bands meet at the Dirac points. The Dirac points are six locations in momentum space, on the edge of the Brillouin zone, divided into two non-equivalent sets of three points. The two sets are labeled K and K'. The sets give graphene a valley degeneracy of gv = 2. By contrast, for traditional semiconductors the primary point of interest is generally Γ, where momentum is zero. Four electronic properties sep…
