Quantum Technology  

In General > s.a. microscopes; technology [molecular devices].

Quantum Dots
* Idea: Structures in which electrons are confined in all three dimensions, so that energies are quantized (like the square well!). Luminescence from single, nm-sized InAs dots excited by a He-Ne laser has been observed.
* Production: Can be made litographically, by etching with electron beams, or by "growing".
* Applications: Read and write data with bursts of laser light; > s.a. technology [solar].
