Configurations of the CNT leads and molecules for the calculation of electronic transmission. [(a) and (b)] Empty nanogap between carbon-capped and H-terminated CNTs. [(c)–(f)] Detailed structure of nanogap created between N-terminated CNT with nucleotides shown explicitly for adenine, cytosine, guanine, and thymine, respectively. In each case, the DNA bases include a sugar-phosphate group as explained in Ref. 1. The distance between the CNT tips was kept at . In this figure, all lead layers of the extended molecule used in the calculation are shown. Nitrogen, carbon, hydrogen, oxygen, and phosphorus atoms are shown in yellow, blue, white, red, and gold, respectively.
Comparison of the characteristics of guanine with N-, C-, and H-terminated CNT leads.
Spectra of eigenenergies of the extended molecule, for various CNT terminations and various nucleotides. Black thin lines are orbitals located at the CNT leads, while red-colored thick lines represent the orbitals located at DNA nucleotides. The Fermi energy is set to zero (dashed horizontal line) in each case.
Current enhancements for various CNT terminations and for four DNA nuelotide types, with 0.1 and transverse biases. The format means .
