Abstract
It has been demonstrated that sulfur treatment using (NH4)2Sx solution provides an effective passivation of the GaAs surface. The effectiven ess of the treatment is dependant on polysulfides S(n)2- concentration s. These treatments being unfortunately not stable with the time, a st abilisation process using a dielectric film overcoathas been investiga ted; a silicon nitride film deposited by the UVCVD technique has been chosen.
