摘要
The study is focused on the improvement of the free electron mobility in Al-doped ZnO films grown by reactive pulsed magnetron sputtering. At optimum growth conditions low-absorbing films are obtained with a Hall mobility of 46 cm(2) V(-1) s(-1), a free electron density of 6.0x10(20) cm(-3), and an electrical resistivity of 2.26x10(-4) Omega cm. The relation between the mobility and free electron density for different growth conditions is discussed in terms of ionized impurity scattering, impurity clustering, and grain boundary limited transport.
