## Abstract On the basis of the LPE GaAs growth rate measurements in which we used current marks of time, the diffusion coefficient and the critical supercooling of arsenic in Ga solution by a semiempirical method was determined. Some knowledge of these parameters is indispensable for investigating
This note presents a method for the determination of the surface diffusion coefficient and surface diffusion flux. The theoretical considerations are based on the Onsager linear theory for the definition of the surface diffusion flux and on the Einstein theorem for the definition of the surface diff
