Quantitative Modeling and Simulation of Quantum Dots
Presentation Materials | 18 Apr 2011 | Contributor(s):: Muhammad Usman
Quantum dots grown by self-assembly process are typically constructed by 50,000 to 5,000,000 structural atoms which confine a small, countable number of extra electrons or holes in a space that is comparable in size to the electron wavelength. Under such conditions quantum dots can be interpreted...
