Description
Summary:Anisotropic carrier transports have been observed in ... and ... films grown on miscut MgO (001) substrates under pulsed-laser irradiations without external bias. The authors discussed the mechanism of the transport process under ultrafast laser irradiation in tilted manganite films. A model of anisotropic diffusion in transient photoresponse is presented. From the microstructure of ... and its photoresponse property in different directions, they can see that the nanometer size domain orientation can modulate the photoresponse signals, indicating a new-type nanometer scale photosensitive source.
