Abstract :
A series of all perovskite oxide p-n heterojunctions (PNHs) as well as perovskite oxide and Si PNHs have been fabricated by a laser molecular-beam epitaxy. The surfaces and interfaces of the PNHs are atomically smooth. The good nonlinear and rectifying I-V characteristics in the PNHs, unusual and high sensitivity of positive magnetoresistance in low magnetic field in SrNbxTi1-xO3/La1-ySry MnO3 and La1-xSryMnO3/Si PNHs, picosecond orders ultrafast photoelectric effect in La1-xSryMnO3 PNHs, as well as ferroelectric property due to the interface enhancement in BaNb0.3 Ti0.7O3/Si PNHs have been observed. It is expected that the further investigation on the PNHs could not only stimulate theoretical study on the mechanisms but also would open up new possibilities in the development and application of electrical devices
