摘要：
Transient photo-induced voltage characteristics have been studied in La0.9Sr0.1MnO3 films on vicinal cut SrTiO3 (0 0 1) substrates. The as-received thin films are epitaxially grown on the substrates and predominated by a single ( 1 01)-oriented growth. Under irradiation of a 308 nm laser pulse the voltage signal is pulsed and the response time agrees with the laser pulse width. The dependence of the voltage peak on the tilting angles from 0 degrees to 45 degrees is further measured. For the c-axis tilt angle, the largest signal does not appear at 45 degrees and the optimum choice is similar to 30 degrees.
