Abstract :
For the first time, thermal polings are performed on Suprasil I samples (Heraeus) under square alternating voltages at variable frequency. Experimental results exhibiting a large increase (×13 compared to a continuous voltage poling) of the second-harmonic signal generated within a sample poled at a frequency of 1 mHz are presented
