Abstract

Gallium selenide (GaSe) thin films on silicon(111) have been first grown by plasma-enhanced chemical vapor deposition (PECVD) using high-purity elemental gallium and selenium as the precursors. The reactive plasma components formed in the gas phase have been studied by optical emission spectroscopy. All grown films have a stoichiometry similar to that of GaSe. An increase in the plasma discharge power to 50 W and higher leads to the formation of an ε-GaSe phase, an improvement in the structural quality of the films, and an increase in the grain sizes with simultaneous grain compaction.

通过等离子体增强化学气相沉积在硅上生长的硒化镓薄膜

摘要以高纯度元素镓和硒为前驱体，通过等离子体增强化学气相沉积（PECVD）技术首次在硅（111）上生长出了硒化镓（GaSe）薄膜。通过光学发射光谱对气相中形成的反应等离子体成分进行了研究。所有生长出来的薄膜都具有与硒化镓相似的化学计量。等离子体放电功率提高到 50 W 或更高时，会形成ε-GaSe 相，改善薄膜的结构质量，并在晶粒压实的同时增大晶粒尺寸。
