Passivated silicon doped chalcogenide composition
A recently granted patent (Publication Number: US11889771B2) discloses a passivated silicon doped chalcogenide composition where hydrogen atoms occupy silicon bonds not attached to chalcogens. The composition includes various chemical formulas such as HSiAsSe, HSiGeAsSe, HSiGeAsSeTe, HSiGeAsSbSe, and HSiGeAsSbSeTe, showcasing the versatility of the invention.
The patent also outlines methods for forming the passivated composition, involving steps like placing the silicon doped chalcogenide composition in a process chamber, passivating dangling silicon bonds by flooding the chamber with forming gas or a hydrogen plasma, purging the gas or plasma, and finally removing the passivated composition. Specific conditions such as temperature, pressure, and duration are provided for optimal passivation, ensuring the efficiency and reliability of the process. These methods offer a practical approach to creating the unique composition with hydrogen atoms occupying specific silicon bonds, opening up possibilities for various applications in the field.
