Radio-Frequency Cantilevers for Scanning Probe Microscopy

We are fabricating radio-frequency silicon nitride cantilevers for the use in scanning probe microscopy. These cantilevers will be used to study dielectric fluctuations above thin polymers films and charging behavior in organic field-effect transistors. Further, we have fabricated doublyclamped cantilevers of similar dimension and constituency and employed a magnetomotive scheme to measure thei...

Insulators at the ultrathin limit: electronic structure studied by scanning tunnelling microscopy and scanning tunnelling spectroscopy

Considerable progress has been made recently, using scanning tunnelling microscopy (STM), scanning tunnelling spectroscopy (STS) and local density functional theory (DFT), in examining the atomic structure and electronic properties of ultrathin insulating films. This article reviews pertinent results to date with special emphasis on ultrathin MgO films on Ag(001) surfaces. Using STS, the layer-...

Single molecules observed by near-field scanning optical microscopy.

Individual carbocyanine dye molecules in a sub-monolayer spread have been imaged with near-field scanning optical microscopy. Molecules can be repeatedly detected and spatially localized (to approximately lambda/50 where lambda is the wavelength of light) with a sensitivity of at least 0.005 molecules/(Hz)(1/2) and the orientation of each molecular dipole can be determined. This information is ...

Scanning tunnelling microscopy of suspended graphene.

Suspended graphene has been studied by STM for the first time. Atomic resolution on mono- and bi-layer graphene samples has been obtained after ridding the graphene surface of contamination via high-temperature annealing. Static local corrugations (ripples) have been observed on both types of structures.

Scanning tunnelling microscopy studies of silicides

We review the topic of scanning tunnelling microscopy (STM) studies of silicides, with an emphasis on fundamental scientific issues that can be addressed using STM and ballistic-electron-emission microscopy (BEEM). The discussion is organized according to the topics of structure (atomic scale precursors, surface reconstructions, bulk structures, interfaces) kinetics and growth (direct atomic me...
