Patent number: 7282732
Quantum dot structures
Original Assignee: STC.UNM
Field of technology: Semiconductors/MEMS
Patent granted on: Tue, 16 Oct 2007
Abstract
Symmetric quantum dots are embedded in quantum wells. The symmetry is achieved by using slightly off-axis substrates and/or overpressure during the quantum dot growth. The quantum dot structure can be used in a variety of applications, including semiconductor lasers.
