Popis: The electrical properties of aluminum silicate (AlSi x O y ) films grown at 120 and 150°C by plasma-enhanced atomic layer deposition were investigated for the application on flexible devices. AlSi x O y films with dielectricconstants of 5.6 and 6.8 exhibited a reduced hysteresis voltage in capacitance-voltage curves compared to Al 2 O 3 films, indicating an improved interfacial quality. The leakage current density for AlSi x O y is comparable to that for Al 2 O 3 . Moreover, the results indicate that the insertion of SiO layers suppresses the film crystallization and the formation of an interfacial layer.
