SEM/STM combination for STM tip guidance
Ultramicroscopy, 1988Abstract A STM capable of coarse positioning in three dimensions was developed for the purpose of examining and reexamining specific locations on the specimen surface. An inertial slider is used to adjust the specimen's position in the horizontal plane, and an inertial rotator is used to adjust the specimen's height. The STM is operated inside an SEM

AbstractScanning tunneling microscopy (STM) and atomic force microscopy (AFM) are capable of providing atomic‐scale images, as well as insights into functional characteristics, of surfaces. Biological materials can be studied by depositing them on appropriate substrates, and samples have been imaged with varying degrees of resolution.

Spectroscopic-Imaging STM (SI-STM)
2017In this chapter I detail the main experimental technique used in this thesis: Spectroscopic-Imaging Scanning Tunnelling Microscopy (SI-STM). I outline the theoretical basis for its use as a tunnelling spectroscopy of superconductors as well as data analysis techniques specific to cuprate superconductors.

Abstract An STM tip has been used to detect photoelectrons emitted from alkali metal-coated aluminium and silicon surfaces whilst within tunnelling range. I–V spectra clearly show a pair of sharp thresholds which are simply related to the tip workfunction, the sample workfunction, and the incident photon energy.

Proceedings, annual meeting, Electron Microscopy Society of America, 1990
Beginning in 1982 when the first images were reported, the development of the scanning tunneling microscope (STM) has revolutionized microscopy in the 1980’s. Although the primary applications are for research on metal and semiconductor surfaces, success in imaging a number of biological samples, mounted on a variety of conductive surfaces, have ...

Soon after the tunneling technique was introduced by Giaever in 1960 [8.1, 2], it became clear that this would become the method of choice to study the quasiparticle density of states in superconductors. Not only could the energy gap be measured with great accuracy, but detailed predictions from the microscopic Bardeen-Cooper-Schrieffer (BCS) theory of

F2C2-STM: Flux-Based Feedback-Driven Concurrency Control for STMs
2014 IEEE 28th International Parallel and Distributed Processing Symposium, 2014Software Transactional Memory (STM) systems provide an easy to use programming model for concurrent code and have been found suitable for parallelizing many applications providing performance gains with minimal programmer effort. With increasing core counts on modern processors one would expect increasing benefits.

In Chap. 2 we showed that a measurement of temperature has to be accompanied with a measurement of voltage as well. We discuss here the experimental consequences of the results of Chap. 2. The best spatial resolution so far achieved in thermal imaging of nanoscale conductors is a few nanometers, which is much coarser than routinely achieved for other ...

Scanning tunneling microscopy (STM) and local probe methods in general offer attractive capabilities for investigations of macromolecules: To observe and study individual objects or molecules in their natural environment, to follow and control molecular processes, and to modify matter on a molecular level.

The local investigation of electrode surfaces and processes by structure-sensitive probing techniques has become an important topic in electrochemistry, since most practically relevant electrochemical systems are characterized by structural and chemical inhomogeneities of the electrode-electrolyte interface. Such inhomogeneities can influence the local
