These excitons exhibit a strong Stark shift (over 60 meV), long lifetime (100 ns), and high diffusivity (1000 cm$^2$/s). This approach is very promising for obtaining the high exciton density needed for Bose condensation of excitons in two dimensions.4 pages, 6 jpeg figuresStrongly Correlated ElectronsMesoscale and Nanoscale Physicstext
