High quality ZnS : Mn thin films grown by quasi-rheotaxy for electroluminescent devices

The object of the present paper is to describe the morphological and crysta lline characteristics of ZnS:Mn thin films grown on different low melting p oint metallic substrates such as Pb, Bi and Bi(1-x)Sbx alloys by a new meth od based on the quasi-rheotaxy technique. In this paper we also prove that the quasi-rheotaxy deposition technique yields high quality ZnS:Mn thin fil ms without the so called dead layer and without the conical pattern typical of the most common deposition techniques.
