[sdiy] DEDs

[Ian Fritz]

Amusing discussion, but once again truth is stranger than fiction. For DEDs 
do, in fact, exist.  Negative photoluminescence and electroluminescence are 
fairly well known phenomena, and have been observed in numerous materials 
and structures, including diodes.  There isn't much information available 
online in this area, but here are a few references:
