"Web3.2 Approximate eﬀective two-band models There are two main reasons for constructing approximate two-band models: First, on physical grounds the high-energy bands (far away from the Dirac point) should not be very important for the low-energy properties of the system. Second, it is often easier to work with 2 × 2matricesinsteadof4× 4matrices. " - Draw a simple flat energy band

WebAn extension of the simple band energy diagram with only the vertical axis labelled as energy, with the horizontal axis unlabelled, is to plot the energy vertically against wave vector, k. From de Broglie's relationship p = hk where p is momentum and h is Planck's constant, h, divided by 2 π. Such plots therefore relate energy to momentum.
