Some Effective Tight-Binding Models for Electrons in DNA Conduction: A Review

Figure 11

Energy bands of the decorated ladder model. (a) The energy bands as a function of 𝑉. (b) The snap shot of the energy bands when 𝑉=1. 𝑘 means the wavevector in units of 𝜋/𝑠 such that −1.0≤𝑘≤1.0, 𝑉 means the 𝜋-electron hopping integral between the interchain sites, and E means the energy in units of 𝑉=1. Here we have taken the values 𝛼=0, 𝛽=0, 𝑎=0.9,and𝑏=1.2.
