[* black] Different tasks call for different tools. If you want to look at some [http://en.wikipedia.org/wiki/Strain_engineering|transistor strain], or some [http://en.wikipedia.org/wiki/Threshold_voltage|gate oxide thicknesses], or even [http://en.wikipedia.org/wiki/Crystal_structure|crystal lattice] orientation, you go for the big gun…
[* black] …the electron gun that's in the new [http://bit.ly/bpKJ4|TEM (transmission electron microscope)]!
[* black] TEM'sTEMs get their high resolution from the small [http://en.wikipedia.org/wiki/Matter_wave|de Broglie wavelength] of [http://sp9.fotolog.com/photo/25/18/94/jimmy_hihi/1291063773811_f.jpg|electrons]. That's quantum mechanics in action!
