基于产教融合“3+1”模式教学改革研究

针对校企联合办班做相应研究,从教改背景、教改目的意义、教改内容及其拟解决的主要问题等,都做出了比较客观的分析,并简要阐述了实施方案和实施计划。     

A thin transition film formed by plasma exposure contributes to the germaniumsurface hydrophilicity

Plasma treatment and 10% NH₄OH solution rinsing were performed on a germanium (Ge) surface. It was found that the Ge surface hydrophilicity after O₂ and Ar plasma exposure was stronger than that of samples subjected to N₂ plasma exposure. This is because the thin GeO_x film formed on Ge by O₂ or Ar plasma is more hydrophilic than GeO_xN_y formed by N₂ plasma treatment. A flat (RMS<0.5 nm) Ge surface with high hydrophilicity (contact angle smaller than 3°) was achieved by O₂ plasma treatment, showing its promising application in Ge low-temperature direct wafer bonding.
