Electrochemical Nanomachining based on Redox Hydrogel Nanofilm: Copper Planarization with nano-precision [PDF]
, 2013 纳米加工要求能够在纳米或分子、原子水平上可控地实现材料的去除、形变或增添。材料去除是目前最常用的加工手段，其特征是将材料表面的一部分与本体之间的化学或金属键打开，并将之移离。按开键原理，相关的加工可大致分为机械、能量束（离子、激光、电子等）、电化学和化学等方法，并有着各自的优缺点，如：机械和能量束法加工精度高，但会造成加工面的损伤，电化学和化学方法则相反。 近年来，飞速发展的各应用领域对加工后的表面质量要求急剧提高，特别是超大规模集成电路制造中的铜互连导线以及高能激光应用中的发/反射镜面 ...

Design and Implementation of Electronic Payment Information Management System Based on CPU IC Card [PDF]
, 2015 人们在各种场景下常常会有小额支付的应用需求，以往大家往往随着携带少量现金或采用银行借记卡来满足各类常见的小额支付需求，现金方式对个人来说非常的不方便，对商户来说现金交易也难以管控，效率较低且存在一定的风险，用银行借记卡来支付的话，由于安全规定的原因需要输入个人密码、打印凭条并签名，对于小额支付较不方便。 因此，如果采用信息技术将随身携带的现金“电子化”，将“实体现金”转化为“电子现金”，就能为消费者个人提供一种更加安全、便捷的支付手段，也能降低收款方现金交易的比例和管理风险，取得双赢的效果 ...

In Situ Uniform Lithium Enrichment for Dense, High‐Performance LLZO Solid Electrolytes
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT A major challenge in garnet‐type Li7La3Zr2O12 (LLZO) system all‐solid‐state electrolytes is the high porosity that typically remains after sintering, which compromises ionic conductivity and degrades battery cycling performance. To address this, we propose an innovative strategy to achieve uniform lithium enrichment on the surface of ...

Research of Ge Junction Technology and Ge Lateral PIN Photodetector [PDF]
, 2015 锗材料因其具有比硅材料更高的载流子迁移率，在通信波段具有高的吸收系数，以及与主流硅工艺相兼容等优点，成为下一代高性能集成电路半导体MOSFET器件沟道的首选替代材料。经过十余年研发，当前Gep-MOSFET的性能已经取得实质性的进展，但相应Gen-MOSFET性能仍未取得突破，除了高k介质与Ge接触产生大量界面态外，还有以下两个原因：首先金属/n-Ge结界面强烈的费米能级钉扎效应和较高的接触势垒引入较大的器件串联电阻；其次Ge中n型杂质扩散严重，激活浓度低，不利于形成n+p浅结。因此，调制金属 ...
