| Research Abstract |
A p-i-n structure with Ge quantum dot superlattice was proposed to detect multi-exciton-generation in solid materials. Amorphous SiCO/Ge quantum dot superlattices were successfully developed by thermal annealing of an amorphous superlattice. Although spin density of the superlattice can be reduced on the order of 10^<18>cm^<-3>, further reduction is required to detect multi-exciton generation.
