Pole figure of the cubic NbN (200) Bragg refection. Upper: growth on -plane sapphire , the two twinning variants of NbN are indexed NbN1 and NbN2. Lower: growth on -plane sapphire . Contour lines underline weak diffraction signal from NbN.
Summary of samples simultaneously deposited for electrical characterization. is the temperature at half height of the normal-superconducting transition. is the square resistance at and is the mean critical current density at . Variations around mean value reflect the spread of measured value on a population of six bridges.
Lattice mismatch of cubic NbN and sapphire derived from experimentally determined in-plane heteroepitaxial relationships.
