Feasibility Study of Directed Self-Assembly of Semiconductor Quantum Dots

Friedman L.H., Xu J., Pennsylvania State University, US

Strain mismatched semiconductors are used to form Self-Assembled Quantum Dots (SAQDs). An important step in developing SAQD technology is to control randomness and disorder in SAQD arrays. There is usually both spatial and size disorder. [...]

Size Effects and Scaling in Misfit Dislocation Formation in Self Assembled Quantum Dots

Friedman L.H., Weygand D.M., van der Giessen E., University of Groningen, NL

Growth islands due to large mismatch strain arising in Stranski-Krastanow (SK) and Volmer-Weber (VW) ﬁlm growth can be used to produce large arrays of quantum dots. This same mismatch strain may also cause misﬁt dislocations [...]
