Nanostruktūrizuotų manganitų kobaltitų sluoksnių magnetovaržinės savybės /
… The resistivity vs. temperature dependences and metal semiconductor transition temperature dependence on the degree of cobalt doping and the size of crystallites in the films were investigated. The resistance relaxation processes in these films after switching-off the magnetic field and the …

Semi-Empirical Studies on Electronic Properties and Applications of Carbon Nanotubes
… limit. Band gap opening/closing is predicted for metallic/semiconducting zigzag nanotubes, while armchair nanotubes remain metallic due to the high lattice symmetry. Next, we demonstrate the possibility of metal-semiconductor transitions in metallic nanotubes under angular perturbations. With the …
