Abstract :
It is found that in laser-induced thermoelectric voltage (LITV) signal in La1-xCaxMnO3 and YBa2Cu3O7-y.H thin films, both the rise-time and decay time are increasing linearly with the total parallel-connected resistance of the load and the film. To obtain fast laser-induced thermoelectric voltage signal, smaller load should be connected in parallel with he film.
