Witryna10 wrz 2013 · It was recently discovered that a transparent n-type (Ba,La)SnO 3 system has electrical mobility as high as 320 cm 2 V − 1 s − 1 at room temperature and superior thermal stability up to ∼500 °C. To understand comparatively the carrier-scattering mechanism in the doped BaSnO 3, we investigate the physical properties of the … Witrynaionized impurities and acoustic phonons, instead of being dom-inated by ionized impurity scattering. Therefore, these results unambiguously demonstrate that mobility can indeed be en-hanced by tuning the carrier scattering mechanism.
