Question

Please describe two experimental methods to measure quantum dot quantization; one by electrical and one by optical method. Do you think it is observable at room temperature?

Answer 1

A quantum dot is a tiny speck of matter so small that it's effectively concentrated into a single point As a result, the particles inside that carry electricity (electrons and holes) are trapped and have well-defined energy levels according to the laws of quantum theory. Tiny really does mean tiny: quantum dots are crystals a few nanometers wide, so they're typically a few dozen atoms across and contain anything from perhaps a hundred to a few thousand atoms. They're made from semiconductor such as silicon (a material that's neither really a conductor nor an insulator, but can be chemically treated so it behaves like either).

two experimental methods to measure quantum dot quantization are electrical and optical
