Long - distance charge transport through DNA . An extended hopping model *
Long-distance transfer of a positive charge through DNA can be described by a hopping model. In double strands where the (A:T)n bridges between the guanines are short (n ≥ 3), the charge hops only between guanines, and each hopping step depends strongly upon the guanine to guanine distances. In strands where the (A:T)n sequences between the guanines are rather long (n ≥ 4), also the adenines ac...
متن کاملHopping conduction in Mn-doped ZnO
The dc and ac conductivities of Mn-doped ZnO were investigated at temperatures from 10 to 100 K. The temperature dependence of the dc conductivity from 10 to 100 K shows an abrupt change at ;18 K, manifesting a much lower activation energy for conduction below 18 K. From 10 to 18 K, the ac conductivity, sac(v), varies as sac(v)5Av s in the frequency range from 10 to 10 Hz with s in the range of...
متن کاملDNA charge transport: conformationally gated hopping through stacked domains.
The role of base motions in delocalization and propagation of charge through double helical DNA must be established experimentally and incorporated into mechanistic descriptions of DNA-mediated charge transport (CT). Here, we address these fundamental issues by examining the temperature dependence of the yield of CT between photoexcited 2-aminopurine (Ap) and G through DNA bridges of varied len...
متن کاملElectronic transport through dsDNA based junction: a Fibonacci model
A numerical study is presented to investigate the electronic transport properties through a synthetic DNA molecule based on a quasiperiodic arrangement of its constituent nucleotides. Using a generalized Green's function technique, the electronic conduction through the poly(GACT)-poly(CTGA) DNA molecule in a metal/DNA/metal model structure has been studied. Making use of a renormalization schem...
