Tilted La1-xCaxMnO3 (0.1 B x B 0.7) thin
films have been grown on vicinal cut LaAlO3 (100) substrate
by pulsed laser deposition. The laser-induced voltage
effect was studied at room temperature with the KrF excimer
laser using as the thermal source. The relationships
between Ca doping level and voltage signal, response time
and anisotropy Seebeck coefficient were established. The
voltage signal and anisotropy Seebeck coefficient increase
at first with increasing Ca doping level, reach a maximum
at the same Ca content around x = 0.5, and then decrease.
The respond time decreases with the Ca concentration
increasing, and changes very little after x = 0.5. The figure
of merit Fm was also the largest at this doping level,
indicating a potential good performance of the photodetector
devices. The variation of intrinsic structural and
transport anisotropy induced by the change of Ca concentration
has been proposed to account for the different LIV
effects observed in LCMO thin films.
