Electrical and physical properties of as-deposited Bi 3.9 La 0.1 Ti 2.9 V 0.1 O 12 (BLTV) ferroelectric thin films on SiO 2/ Si (100) substrates were improved by low temperature supercritical carbon dioxide fluid (SCF) process treatment. The as-deposited BLTV ferroelectric thin films were treated by SCF process which mixed with propyl alcohol and pure water. The memory windows increased in C-V curves, and the oxygen vacancy and defect in leakage current density curves were obtained after SCF process treatment. Finally, the improvement properties of as-deposited BLTV thin films after SCF process treatment were investigated by XPS, C-V, and J-E measurement. The mechanism concerning the dependence of electrical properties of the ferroelectric thin films on the SCF process was investigated and discussed.

Supercritical Carbon

This paper investigates the effect of water serving as entrainer on the dyeing of wool fabrics in supercritical carbon dioxide. Compared with previous supercritical dyeing methods, addition of water makes the dyeing process more effective under low temperature and low pressure. During dyeing process, dyestuff can be uniformly distributed on fabrics?s surface due to water interaction, as a result coloration is enhanced while color difference is decreased.
