[edit] Diagram
We need a diagram of a standard HEMT device and not just a PHEMT. Would someone be able to produce this? Mike 09:07, 21 May 2007 (UTC)

[edit] History
Can anyone add a section on the history of the HEMT and in particular who lays claim to it - I believe it was a chap at Fujitsu. History of HEMT Transistors http://eesof.tm.agilent.com/docs/iccap2002/MDLGBOOK/7DEVICE_MODELING/3TRANSISTORS/0History/HEMTHistory.pdf Which says "Dr. Takashi Mimura, the inventor of HEMT, is currently a fellow of Fujitsu Laboratories."
But elsewhere there were scientists working on GaAs MODFETs and devices with various other names. I recall Linh Nuyen who founded Picogiga published papers on his TEGFET transistors when he was at Thomson CSF the French electronics company.
Linh Nuyen, the Company's Chairman and CEO, was the co-inventor of the High Electron Mobility Transistor ("HEMT").
