In this work the development of a low-temperature scanning probe microscope and the investigation of thin insulating films at the atomic limit is presented. The scanning probe microscope has been designed in a modular way to provide large flexibility for t ...
Employing higher oscillation modes of microcantilevers promises higher sensitivity when applied as sensors, for example, for mass detection or in atomic force microscopy. Introducing a special cantilever geometry, we show that the relation between the reso ...
SU-8 is a photoplastic polymer with a wide range of possible applications in microtechnology. Cantilevers designed for atomic force microscopes were fabricated in SU-8. The mechanical properties of these cantilevers were investigated using two microscale t ...
This paper describes the characterization and application of electrically insulated conductive tips mounted on a cantilever for use in an atomic force microscope and operated in liquid. These multifunctional probes were microfabricated and designed for mea ...
We present an automation technique for the growth of electron beam deposited tips on whole wafers of atomic force microscope cantilevers. This technique uses pattern recognition on scanning electron microscope images of successive magnifications to precise ...
In this letter, we describe the on-demand dispensing of single liquid droplets with volumes down to a few attoliters and submicrometric spacing. This dispensing is achieved using a standard atomic force microscope probe, with a 200 nm aperture at the tip a ...
Crystals of hexamethylenetetramine (HMT) with aliphatic dicarboxylic acids in 1:1 molar ratio exhibit different behaviour depending on the number n of carbons in the aliphatic chain. For n=8 and 10, incommensurate phases have been observed, while for n=9, ...
Structural information on membrane proteins is sparse, yet they represent an important class of proteins that is encoded by about 30% of all genes. Progress has primarily been achieved with bacterial proteins, but efforts to solve the structure of eukaryot ...
During the sliding of an atomic force microscope (AFM) tip on a rough hydrophilic surface, water capillary bridges form between the tip and the asperities of the sample surface. These water bridges give rise to capillary and friction forces. We show that t ...
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 ...
