摘要: Reasons have been found for thinking that the minimum diameter of channels a given length to support superconductivity at room temperature through films oxidised atactic polypropylene (OAPP) is considerably larger than in model Bose condensation an array nanofilaments [D.M. Eagles, Phil. Mag. 85, 1931 (2005)] used previously. This was introduced interpret experimental results dating from 1988 on OAPP. The are thought be believed before because, N-S-N system where superconductor consists single-walled carbon nanotubes, resistance, good contacts, R_Q/2N, N number nanotubes and R_Q=12.9 kOhm [See e.g. M. Ferrier et al., Solid State Commun. 131, 615 (2004)]. We assume this would 2R_Q/N triplet with all spins same direction no orbital degeneracy, which may case Hence one infer filaments resistance. In present model, E(K) curve bosons taken Bogoliubov form, but less steep initial linear term dispersion T_c occurs low T. form different simple plus quadratic dispersion, steeper slope, my 2005 paper. A combination theory data has find approximate constraints parameters appearing theory.
