“…The SPELS instrument employed in this study employed a STM head based on the "pocket size" STM design of Lyding and others, [6][7][8] which provides good access to the sample surface. The STM tips were produced by etching a 0.5 mm polycrystalline tungsten wire in a two-molar solution of NaOH; the tips were cleaned in situ by electron bombardment heating, and sharpened by argon ion sputtering.…”

We report scanning probe energy loss spectroscopy (SPELS) measurements from a roughened Si(111) surface in ultrahigh vacuum. The experiments, which utilize a scanning tunneling microscope tip in the field emission mode as the electron source, establish that the spatial resolution in SPELS is better than 50nm. The spectral maps acquired indicate different contrast mechanisms for the inelastically scattered and secondary electrons identified in the energy loss spectrum.

“…With the development of low temperature STM, coarse positioning devices or so-called nanopositioning stages based on piezoelectric actuators 8 were introduced. 9 The three most frequently used configurations are the beetle setup, 10 the inertial slip-stick slider, 11,12 and the friction motor. 13 Low temperature scanning probe microscopes with XY coarse positioning of the sample are commercially available 14 but their eddy current damping mechanisms prevent magnetic field investigations.…”

We describe the design and development of a compact low temperature XY stage scanning tunneling microscope dedicated to operation at low temperatures, in high magnetic fields, and in an ultrahigh vacuum environment. The system features a homemade compact scanning tunneling microscope ͑STM͒ head coupled to an inertially driven horizontal slider which allows a two-dimensional coarse positioning of the tip over 6 ϫ 3 mm 2 with submicronic resolution. We also describe the geometry used to avoid coupling between the three-dimensional coarse and fine movements. To demonstrate the mechanical stability of the STM we display atomic resolution and large scale imaging. We illustrate the capabilities of our system by performing scanning tunneling spectroscopy on PbMo 6 S 8 microcrystals.

We have designed and fabricated a cryogenic scanning tunneling microscope for probing lithography defined nanometer-scale devices. The piezoelectric double tube is capable of scanning an area up to 22 mϫ22 m, while maintaining atomic resolution. In addition, the sample mount has a 5 mmϫ4 mm traveling range. Most importantly, the system is compact and, as a result, it can be inserted into the bore of a superconducting magnet. In this work, we demonstrate a unique application of scanning tunneling system, i.e., the scanning tip is in direct contact with the sample. The spectroscopic information therefore reflects the true characteristics of the devices under test, unlike the typical case where the tunneling barrier through vacuum imposes a large series resistance, on the order of 10 9 ⍀. The design as well as the operation of this compact scanning tunneling microscope is described.
