Title: Electropulsing induced phase transformations in alloys and thin films of TCO and TE semiconductors
Abstract: Based on systematic studies of equilibrium and non-equilibrium transformations and the stress induced transformations, studies of electropulsing induced phase transformations of alloys and thin films of semiconductors, such as transparent conductive oxides (TCO) and thermoelectric (TE) materials: Bi-Te, AZO have been carried out. As one of the advanced processes, electropulsing increases plastic elongation of alloys about 437%. Under adequate electropulsing, phase transformations and microstructural changes were tremendously accelerated by factors of at least 6000 times, compared that in conventional aging processes in alloys. The electropulsing induced circular phase transformations ( quenching – up quenching , up quenching – quenching, … quenching – up quenching – quenching – up quenching etc. ) and preferred crystal orientation changes are quantitatively detected to complete within several seconds, in alloys and the thin films. Adequate electropulsing increases electric conductivity of the thin-films for 44.6% and 28.5%, respectively. The quantitatively detected multi-circulation of both the phase transformations and the preferred crystal orientation changes makes it possible to monitor microstructural changes and to enhance physical and optical properties of the thin films. The researches road map went through various aspects of the physical metallurgy, included thermal metallurgy, mechanical metallurgy, electro-metallurgy and electro-mechanical metallurgy, and was effective in studying and exploring application of the thin films of semiconductors, as shown in following figure
