介绍了一种用 1-烯烃对氮化镓表面进行热诱导功能化的工艺。所得的功能化层通过原子力显微镜和X射线光电子能谱进行表征,并与不具有和具有光化学生成的功能化层的参考样品进行比较。由此产生的层在基于 GaN 的生物传感器的功能化方面显示出非常有前景的特性。根据实验结果,估计了功能化层的重要特性,并提出了可能的化学反应方案。
A thermally induced functionalization process for gallium nitride surfaces with 1-alkenes is introduced. The resulting functionalization layers are characterized with atomic force microscopy and X-ray photoelectron spectroscopy and compared to reference samples without and with a photochemically generated functionalization layer. The resulting layers show very promising characteristics as functionalization for GaN based biosensors. On the basis of the experimental results, important characteristics of the functionalization layers are estimated and a possible chemical reaction scheme is proposed.
