Some of the work I contributed to in Le Mans is getting out. You can find a preprint Here. The work is titled: 'Domain-engineered ferroelectric BiFeO3 thin films for efficient bias-free THz emission' It consists in a very nice comprehensive study of THz emission in single-domain and striped-domain BiFeO3. The material shows a very good THz emission, whose effect is enhanced by ferroelectric domain patterning.
