“…In the last several decades, a research area based on polycrystalline chalcogenides [22][23][24][25][26][27][28][29][30][31][32][33] and their solid solutions for IR photodetectors and emitters [21][22][23][24][25][26] has been successfully developing. The optimization of technological processes is accompanied by the sensitization of materials and the creation of protective oxide shells [28][29][30][31][32] consisting of different chemical compounds, namely PbO x , PbSeO 3 , bi-and tetra-oxyselenites and oxyselenates (2PbO•PbSeO 3 , 4PbO•PbSeO 3 ) [29].…”

A model is developed for the formation of porous intragranular architectonics of nanostructured polycrystalline layers of lead chalcogenides for photodetectors and IR emitters. The layers are obtained under the conditions of thermal evaporation in a quasi-closed volume by the “hot wall” method followed by sensitizing heat treatment in an iodine-containing atmosphere. Model concepts are developed considering the experimental results of studying the intragranular structure of lead chalcogenides through original combined AFM methods over the cross-section of porous grains (cores) encapsulated by an oxide shell (lateral force microscopy and local tunneling I–V spectroscopy).
