Trek Talk and the DOE

Remember the wonderful tech-talk that the writers were so fond of on Star Trek?  Just reflect on the melodious qualities of this line:   “We’ll be retuning phasers to higher EM base emitting frequencies to try to disrupt their subspace field.”  Ah, music.  And who among us has not slipped into an aesthetic trance mulling over the metaphysical implications of  the Transporter’s Heisenberg Compensators?

So, when I stumbled across this one on an electronics trade mag website, I just had to post it for you all to enjoy. 

Sandia National Laboratories’ project, “Semi-polar GaN Materials Technology for High IQE Green LEDs,” seeks to improve the internal quantum efficiency (IQE) in green nitride-based LED structures by using semi-polar GaN planar orientations for InGaN multiple quantum well (MQW) growth. The DOE said that these semi-polar orientations have the advantage of significantly reducing the piezoelectric fields that distort the quantum well band structure and decrease electron-hole overlap. At the end of this program, Sandia National Laboratories expects MQW active regions at 540 nm with an IQE of 50%, which with an 80% light extraction efficiency should produce LEDs with an external quantum efficiency of 40%, or twice the estimated current state-of-the-art.

Now that’s poetry.

  1. It IS? Poetry?

    Well, I wouldn’t know. Not a poetic bone in my body.

  2. I LOVE it!! I’d like to hear someone “freestyle” it. 🙂

  3. It’s all Geek to me.
