A. Passaseo et al., Wavelength control from 1.25 to 1.4 mu m in InxGa1-xAs quantum dot structures grown by metal organic chemical vapor deposition, APPL PHYS L, 78(10), 2001, pp. 1382-1384
This letter reports on the realization of long-wavelength InGaAs quantum do
ts (QDs) fabricated by metal organic chemical vapor deposition. By controll
ing the In incorporation in the QD layers and/or in the barrier embedding t
he QDs, we are able to tune the wavelength emission continuously from 1.25
to 1.4 mum at room temperature. Efficient stacking of dots emitting at 1.3
mum is also demonstrated. (C) 2001 American Institute of Physics.
