What is CdTe and CdTe: Cl vapour growth in a semi-closed system about?

## Undoped and chlorine-doped CdTe single crystals of 2.4 cm diameter were grown from the vapour phase by a modified Markov method. Boundary conditions for the control of partial pressures were realized applying a heat sink at different temperatures. The influence of the sink on dopant incorporation was investigated by photoluminescence. Transitions of free and bound excitons dominate the PL spectra in cases of undoped CdTe. The characteristic luminescence of the A-centre was identified in CdTe : Cl. Alpha measurements yielded a product of carrier mobility and lifetime of 2 x 10m4 cm\*/V.
