... interfaces of grains. As the annealing temperature was increased, the root-mean-square [RMS] surface roughness of pentacene-doped PEDOT:PSS films increased as well because the grain size has increased. For ... devices that the measured hole mobility increases along with the increase of the annealing temperature, starting to increas e at a low temperature and satura...

... error than any one of the basic measures. As the result of this orthogonal rotation, then, we obtained several factors. Each of them was represented as a combination of all nine measures of improvement. ... sensitivity of the factors' mean values was examined by comparing the "factor analysis cohort" calculations for each of the 4 factors with all...
