| Outline of Final Research Achievements |
Sugar crystal was proposed as a novel THz-wave emitter material, and the crystal growthin large size was performed and the property of crystal was evaluated in THz-region.
Prior to the crystal growth, it was disclosed that stereoisomer and crystallized particle size in sugar powder preliminary used for the crystal growth can be quantitatively determined by THz time-domain spectroscopy.
The single sugar crystal with the size of 2mmx5mm was obtained by the seeding with monitoring laser light during extraction of the sugar from the super-saturated solution and the growth in optimum condition determined by the in-situ observations. THz-emission peak at 1.34THz was speculated by numerical analysis for the property obtained for the sugar crystal in THz-region.
