The optical, dielectric, electric, structural, surface, and interface properties of Nd2O3 films are investigated using a wide range of characterization techniques that reveal smooth Nd2O3 films of cubic structure, wide bandgap (6 eV), high-k (11), and low leakage currents (<0.5 nA cm−2). Thin film transistors (TFTs) using ZnO channels show excellent characteristics, such as high electron mobility, in excess of 65 cm2 V−1 s−1, high on/off current ratio in the range between 106 and 107, and negligible hysteresis. The devices demonstrate excellent constant bias stress and air stability air, i.e., only a small decrease of the electron mobility and threshold voltage (<12%). In addition, the excellent uniformity and homogeneity that is demonstrated combined with the relatively low deposition temperature (compared with those used with the vast majority of the vacuum based techniques employed) in ambient air on glass substrates indicates the potential for the rapid development of metal oxide-based TFTs employing gate dielectrics also grown from solutions at low manufacturing cost.",
