| Outline of Final Research Achievements |
We have studied theoretically and experimentally on material instability under illumination. Targets are low dimensional materials, where fundamental electronic excitations, excitons, are automatically self-trapped. We have found the followings:
1) Second exciton creation with a smaller energy is possible in during the lattice relaxation caused by a first exciton creation. 2) New type of alloys phenazine-(TCNQ1-x FTCNQx) are successfully synthesized. Although x=0.4 alloy shows the same crystal structure as of x=0 and 1.0, alloys with x=0.6 show molecular dimerization. 3) Single crystal diacetylene has been found to show structural changes accompanied by symmetry changes, suggesting structural instability might depend on conformation of side chains.
