Ring formation of transition metal trichalcogenide TaSe3 using vapor liquid process

Abstract

The synthesis of TaSe3 ring-shaped crystals displaying the coffee ring effect is investigated. By recrystallizing TaSe3 microcrystals dissolved in droplets of condensed Se gas, ring-shaped crystals were successfully grown. This novel method for ring formation effectively addressed the issue of connecting the edges of the crystal. Consequently, the synthesis method has the capability to grow MX 3 ring-shaped crystals in any location where droplets can condense, can now be grown in specific locations, thus creating opportunities for advancements in electronic component development.
