| Research Abstract |
The present study has been aimed to reveal the correlation between lattice strains and electric conductivities in nanometer-scale areas. The results are the followings. (i) A method to determine lattice parameters and parameters characterizing lattice bending simultaneously with a spatial resolution of 10nm has been developed. (ii) A GUI-based software, in which the present algorithm is implemented, has been developed. (iii) An automated system for the pattern acquisition with a 2D beam-scanning and the lattice-strain analysis has been constructed. (iv) A method to determine the 3D lattice-strain-field from the HOLZ rocking curves using the Fourier iterative phase retrieval method has been developed. (v) A highly precise method to determine lattice parameters at the vicinity of interfaces of hetero-layers using the nano-beam diffraction technique has been developed. (vi) A high-voltage electron microscope has been used to apply the present method to relatively thick specimens, which has less influenced by the surface relaxation due to specimen thinning。(vii) I-V curves and lattice strains have been measured simultaneously by using an STM holder and HOLZ line analysis.
