OPTICAL IN-SITU CHARACTERIZATION OF DEPOSIT FORMATION UNDER ALTERNATESUPPLY OF DIETHYLZINC AND CO2 AT ROOM-TEMPERATURE

Large (of a percent-order) reflection intensity changes in the early s tages of deposit formation on glass surfaces under alternate supply of diethylzinc and CO2 have been obtained at room temperature. In the me asurements, a nearly normal incident irradiation of a 632.8 nm He-Ne l aser was used. Short-period oscillations superimposing the diethylzinc -induced reflectance signal have also been detected. The findings are interpreted in terms of the peculiarities of the deposit roughness evo lution.
