Weird & wonderful Quantum Topological Insulators

[gary]

The July 20011 edition of the Institute of Electrical & Electronic Engineers (IEEE)
Spectrum Magazine has an article by Joel E. Moore of the University of California,
Berkeley entitled "Topological Insulators".







On a personal note, I also found the article interesting because it mentions
during its introduction in several places both "modulation doping", which creates
a two-dimensional electron gas at the interface between two semiconductors of
different bandgaps and "quantum wells", both of which were discovered by my
previous boss.

Modulation doping is used in the ubiquitous High Electron Mobility Transistor (HEMT).
If you have a mobile phone, then you will have one in your pocket.

Hey Gary, how did you manage to pick up a copy of Spectrum from July 20011:):P

Didn't know you owned a TARDIS:):P

Interesting article though:)

Thanks Carl,

Where else but on IceInSpace can you read all the news before it happens. :lol:

Glad to hear you found the article interesting!

WAY before it happens:):):P

I think, by 20011, they'll have progressed a fair way beyond topological insulators or anything like the present semiconductor theory:):)

They would have a time machine, travel back to 2011, and correct the typographical error.:thumbsup:

And probably take their copy of Spectrum back to their own time, just in case someone now, like the US military, get a hold of it and start trying to reverse engineer what they find in it:):P

Mind you, it'd be more than likely a case of Arthur C Clarke's adage about a sufficiently advanced technology being like magic:):)
