Simultaneous Kinetics of Drops and Excitons in Silicon during the Drop Formation

Abstract
Using an homogeneous excitation, the simultaneous kinetics of drop and exciton luminescence are measured during the initial regime of drop formation in silicon. Theoretical simulations of the exciton density developped, do not fit well the experimental lineshapes. From an analysis of the experimental curves, it is suggested that a coalescing effect of drops must be taken into account to improve the fit of the experimental kinetics by the theoretical model.
