Stemming reduces inflected words to their stem or root form.
For example the words fishing, fished,fish, and fisher are reduced to the root word,fish,
so a search for fisher returns all the different variations
Returns only one member of a family of patents
Include Non-Patent literature in results

Appl.No PCT/JP2001/005769 Applicant TOYODA GOSEI CO., LTD. Inventor WATANABE, Hiroshi
A III Group compound semiconductor light emitting element which emits a light of a wave length of 360 to 550 nm and has a light emitting layer containing portions comprising AlGaN layers and, sandwiched between them, an InGaN layer. The output of the light emitting element is improved by controlling the film thickness, growth rate and growth temperature for the InGaN layer as a well layer and the film thickness of the AlGaN layer so as to optimize them.
