Figure 1From: La 1−xCa x MnO3 semiconducting nanostructures: morphology and thermoelectric propertiesScanning electron microscopy images after different temperature treatments for 12 h. (A) 900°C, (B) 650°C, and (C) 230°C. (D) X-ray diffraction spectra of La 1−xCa x MnO3 nanostructures (x=0.05). The red lines refer to the perosvkite phase diffraction pattern.Back to article page
