Quantitative Modeling and Simulation of Quantum Dots

18 Apr 2011 | Notes | 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 …
