Figures

Image of FIG. 1.
FIG. 1.

(a) PL spectra of the exciton transition in an epilayer measured at different temperatures from 10 to . (b) PL spectra of the exciton transition in a epilayer measured at different temperatures from 10 to . The dissociation of the bound excitons into the free excitons with increasing temperature is clearly seen between 10 and . The spectra are vertically shifted for a better illustration in (a) and (b).

FIG. 2.

Temperature dependence of the exciton emission peak position in the epilayers. The solid lines are the least-squares fit of data with (a) Eq. (1) and (b) Eq. (2). The error bars are indicated for two representative measurement temperatures.

FIG. 3.

Temperature dependence of the exciton emission peak position in the epilayer. The solid lines are the least-squares fit of data with (a) Eq. (1) and (b) Eq. (2). The error bars are indicated for two representative measurement temperatures.

Image of FIG. 4.
FIG. 4.

PL emission linewidth as a function of temperature for and epilayers. The solid lines are the least-squares fit of data with Eq. (3) for (a) and (b) . The error bars are indicated for two representative measurement temperatures.
