Figure 7From: High electron mobility and low carrier concentration of hydrothermally grown ZnO thin films on seeded a-plane sapphire at low temperature RT PL spectra of ZnO films. RT PL spectra of ZnO films grown on CVD ZnO seeds at temperatures of (a) 70°C, (b) 80°C, and (c) 90°C, respectively. (d) The ratio of the intensities of both peaks.Back to article page
