PREPARATION OF SEMICONDUCTOR SUPERLATTICES FROM LB PRECURSOR

Semiconductor nanoparticles were produced by exposing fatty acid salt Langmuir-Blodgett films to the atmosphere of H2S. Particles of differe nt materials, such as CdS, PbS, MgS were formed and studied. Particle aggregation was used for producing thin semiconductor layers and super lattices. Alternating LB films of fatty acid salts with different meta ls were deposited, varying their thickness. Film structure was investi gated by electron microscopy. The measurements revealed that semicondu ctor superlattices with different alternating layers were formed. (C) 1998 Elsevier Science S.A. All rights reserved.
