Combinatorial Synthesis and Evaluation on Thermoelectric Films

Abstract

Combinatorial technology is a powerful tool for new material exploration. Some new combinatorial technologies, such as combinatorial laser molecular beam epitaxy (CLMBE) and combinatorial pulsed laser deposition (CPLD), were introduced in the paper. La1-xCexVO3 (0≤x≤1) composition-spread films were fabricated successfully by CPLD, while their thermoelectric properties and structures were evaluated by the multi-channel thermoelectric measurement system and concurrent X-ray analysis respectively. Combinatorial technologies are proving to be an efficient, low-cost tool in synthesis and characterization of thermoelectric composition-spread films.

Temperature-Induced Phase Transitions of Fe-Ga Alloys for Sensors

“…The saturation magnetization of the Fe -Ga alloy is proportional to the crystallite size. Notably, the magnetic properties of Fe-Ga alloys are influenced significantly by their structural ordering (24,31,46). The lower coercivity in Fe-17Ga alloy denotes that the alloy is easier magnetize and have higher saturation magnetization.…”

“…The distance between Fe atoms determines their magnetic moments (29,30). The Ga-rich phase boosts the remanent and saturation magnetization (31). This work is proposed to study whether the magnetostrictive property enhances with further addition of Ga and phase transitions with different compositions of Fe-Ga alloys (32)(33)(34).…”
