http://www.physorg.com/news81606067.html Strictly since it only has two terminals (one for p one for n) it may not qualify as a "transistor" (which uses an independent electric gate as a third terminal) but is more like a quantum-confined diode.

Well, yes. To be qualified as LET, it should have three lead, but it could have the same material as a VCSEL lasing material ( GaAs/AlGaAs : Gallium Aresnide / Aluminum Gallium Aresnide Heterostructure) - on other hand, you can use GaN/InGaN or AlGaN/InGaN for Ultraviolet laser radiation but it's not cheap right now - why? the regular blue laser diode (although short in supply) currently costs from $400 to $2000.
