Conductive atomic force microscopy (C-AFM) was used to study the dielectric breakdown of SiO/sub 2/ layers at a nanometric scale. First, bare oxide regions were stressed and broken down using the tip as the metal electrode of a MOS structure. The results s ...
Scanning electrochemical microscopy (SECM) was used to characterize addressable microelectrode arrays patterned with 25 regularly spaced (100 μm center to center) 10 μm diameter platinum microdisks. Both the feedback mode and the substrate generation/tip c ...
To improve the performance of atomic force microscopes regarding speed and noise sensitivity, it is important to consider the mechanical rigidity of the actuator (scanner), and the overall mechanical structure. Using finite element analysis in the design p ...
Dispersion relations of the s-p derived surface state on (111) surfaces of silver and copper have been measured using low-temperature scanning tunneling microscopy and spectroscopy. For silver as well as for copper we find a significant deviation from a pa ...
High-density arrays (5 x 10(6) cm(-1)) of parallel nanowires have been grown using the vicinal Pt(997) surface as a template. Single monatomic rows of Ag and Cu can be deposited with subrow precision. We demonstrate real-time monitoring and characterizatio ...
Al0.1Ga0.9N(5nm)/GaN(2nm) and In0.2Ga0.8N/GaN quantum wells (QWs) grown on GaN/sapphire have been studied by cathodoluminescence (CL) spectroscopy and imaged using an experimental setup especially developed for scanning near-field CL microscopy, which comb ...
A new method for measuring local interfacial impedance properties with high lateral resolution was developed by combination of electrochemical impedance spectroscopy (EIS) with scanning electrochemical microscopy (SECM). Alternating current scanning electr ...
A dual-axis, raster-scanning laser display based on a monolithic micromachined scanner is presented. The scanner consists of a mirror located at the end of a thermally actuated bimorph beam. The novelty of the device is that the two orthogonal angular moti ...
A dual axis, raster-scanning laser display based on a monolithic micromachined scanning mirror is presented. The scanner consists of a micromirror located at the end of a thermally actuated bimorph beam. The novelty of the device is that an "L"-shape canti ...
