A Combined Technique of Laser and STM For Electrochemical Micro- (Nano-)Fabrication

利用rAMAn—STM联用系统引人激光配合STM开展电化学纳米材料加工.该方法的特点为它不仅可进行纳米加工，还可立即进行原位测量所加工的材料的形貌及结构，继而原位改进加工条件。A novel technique of the combination of laser and STM is introduced to micro-- and nano--Fabrication in an electrochemical cell.Both the STM tip and the incident lllser can be utilized to induce electrodeposition and electro-polymerization at nano-or microscale on electrode surFaces.This technique can be applied Further as a multiple tool For Fabrication and in--situ measurement, i.e.both the topography and structure of the pattern just Fabricated can be measured in--situ without changing electrochemical condition.国家自然科学基金委优秀中青年人才基金;国家教委跨世纪人才基

Surface Raman Spectra Obtained from Various Electrodeposited Transidon Metals

各种电沉积的过渡金属上的表面拉曼光谱高劲松，任斌，黄群健，田中群（厦门大学化学系，固体表面物理化学国家重点实验室，物理化学研究所，厦门３６１００５）七十年代中期发现的表面增强拉曼散射（ＳＥＲＳ）效应，曾激起人们将拉曼光谱技术应用于表面（界面）吸附、结...Good quality potential-dependent surface Raman spectra of pyridine were obtained for the first time from a series of transition metals,e. g.,Fe,Co,Ni,Ru,Rh,Pd and Pt,which were electrodeposited on non-SERS-active substrates.The influences of the applied potential and the nature of metal on the adsorption behaviors were discussed briefly.This result illustrates that Raman spectroscopy is becoming a more general and powerful tool to study various electrochemical interfaces.作者联系地址：厦门大学化学系Author's Address: State Key Lab. for Phys.Chem.of Solid Surf.,Deptof Chem.,Inst.of Phys..Chem.,Xiamen University,Xiamen 36100
