Passivation of semiconductor and metal surfaces with organic monolayers

自本研究期的第一年（2007财年）起，我们继续与东北大学、熊本大学和斯坦福大学（美国）合作进行实验。在2007财年，我们订购了设备，设备最终交付。在2008财年，我们取得了相当多的基本发现，其中以同步辐射辅助下改性硅“亲水性”驱动力的发现为主导。至于铝表面的钝化，在2009财年之前取得了实质性进展。该技术已申请专利。红外光谱的发展，尽管在样品制备上有一些困难，但最终得到了超薄分子层（厚度小于1nm）的强烈信号，这已被发现适用于水溶液中的有机分子，如磷脂。

Since the first year of this research period, FY2007, we continued the experiments collaborating with Tohoku Univ., Kumamoto Univ. and Stanford Univ. (USA). In FY2007, we ordered the equipments, and the equipments were delivered in the end. In FY2008, we achieved quite a few basic findings, led by the finding on the driving force of "hydrophohicity" of modified Si aided by synchrotron radiation. As for passivation of aluminum surfaces, a substantial progress was made until FY2009. This technology has been filed for patent application. The development infrared spectroscopy, despite some difficulties in sample preparation, ended up with strong signals of ultrathin molecular layers (less than 1 nm thick), which has been found to be applicable for organic molecules, such as phospholipids, in aqueous solution.
