This article describes the use of scanning catalytic probe lithography for nanofabrication of patterns on self-assembled monolayers (SAMs) of reactive adsorbates. Catalytic writing was carried out by scanning over bis(omega-tert-butyldimethyl-siloxyundecyl)disulfide SAMs using 2-mercapto-5-benzimidazole sulfonic acid-functionalized gold-coated AFM tips. The acidic tips induced local hydrolysis ...

Reduction of graphene oxide at the nanoscale is an attractive approach to graphene-based electronics. Here we use a platinum-coated atomic force microscope tip to locally catalyse the reduction of insulating graphene oxide in the presence of hydrogen. Nanoribbons with widths ranging from 20 to 80 nm and conductivities of >10(4) S m(-1) are successfully generated, and a field effect transistor i...

High-resolution lithography often involves thin resist layers which pose a challenge for pattern characterization. Direct evidence that the pattern was well-defined and can be used for device fabrication is provided if a successful pattern transfer is demonstrated. In the case of thermal scanning probe lithography (t-SPL), highest resolutions are achieved for shallow patterns. In this work, we ...

We succeeded in extending local oxidation to in situ negative patterning. HF/EtOH was used as both gap-bridging electrolyte and oxyanion source. EtOH and HF were found to be able to accelerate the growth of silicon oxide and simultaneously etch grown oxide, respectively. These findings are expected to open new possibilities in utilizing local oxidation nanolithography in order to directly fabri...

Abstract Despite of tremendous potential multiphoton lithography (MPL) in laboratorial and industrial applications, simultaneous achievement high throughput, accuracy, design freedom, a broad range material structuring capabilities remains long-pending challenge. To address the issue, we propose an acousto-optic scanning with spatial-switching multispots (AOSS) method. Inertia-free nonlinear sw...

Scanning Hall Probe Microscopy (SHPM) is a scanning probe microscopy technique developed to observe and image magnetic fields locally. This method is based on application of the Hall Effect, supplied by a micro hall probe attached to the end of cantilever as a sensor.  SHPM provides direct quantitative information on the magnetic state of a material and can also image magnetic induction under a...
