Introduction
The SPM-M Kit combines the MadPLL instrument package with Mad City Labs high resolution nanpositioning systems to form a high performance, closed loop, scanning Akiyama probe or tuning fork AFM. The seamless integration of hardware combined with the built-in automated control of MadPLL means that you can concentrate on getting results, not tweaking parameters. Applications for the SPM-M Kit include nanoscale characterization and nanoscale fabrication applications such as optical antennas, nano-optics, semiconductors, data storage, and more. The SPM-M Kit is ideal for research and teaching laboratories offering high performance, versatility, simplicity and excellent value.At left: Schematic of a typical AFM instrument based on the SPM-M Kit.The SPM-M Kit includes: MadPLL Instrument Packagedigital phase lock loop (PLL) controllerprobe mounting boardsfive quartz tuning forksNano-SPM200 nanopositioning stage (XY)Nano-OP30 nanopositioning stage (Z)3 axis closed loop Nano-Drive controllerZ axis open loop/close loop switch (OCL option)AFMView SoftwareAFMView TutorialAdapter plate between probe mount board and Nano-OP30Application note: "AFM Kit with manual positioning"Application note: "Tungsten tip etching station"MadPLL is a powerful instrument package that allows the user to create an inexpensive, high resolution resonant scanning probe microscope using Mad City Labs nanopositioning systems. The MadPLL package includes a digital phase lock loop (PLL) controller, software, sensor amplifier board, and resonant probe mounting board. MadPLL includes five (5) each of the vertical, horizontal, Akiyama, and blank probe boards. In addition, each unit is shipped with five (5) tuning forks. Additional probe boards and tuning forks can be purchased separately.Available options:Double walled isolation enclosureCoaxial illuminatorMotorized or manual Z-axis approachMotorized or manual XY-axisCameraSPM baseplateSPM Etch KitNot included:These items are described in the application note and are listed in the Bill of Materials (BOM)L-BracketFasteners or clampsRecommended additional items:Vibration isolation table
Absolute Metrology
The SPM-M Kit incorporates the Nano-SPM200and Nano-OP30with a three axis Nano-Drivecontroller for closed loop nanopositioning in X, Y, and Z. These systems incoporate Mad City Lab's proprietary PicoQ sensor technologyfor closed loop feedback control, offering significant advantages in terms of image quality, accuracy and repeatability over open loop scanners. The sensor signal from all three axes can be read during AFM scans via the analog output signal or USB, thus minimizing the effects of hysteresis, curvilinear motion, and creep that result if data are analyzed using assumed commanded positions. Using position information from closed loop sensors also eliminates the need to scan a calibration grid in XYZ before scanning every sample. Scanning with closed loop nanopositioners saves time and improves image quality. Closed loop feedback also allows the nanopositioners to move and return to commanded positions with much more reliability than open loop systems, allowing users to return to previously scanned features for further analysis.

One way to produce sharp probe tips suitable for building an AFM is to electrochemically etch tungsten wire. This method can produce a tip radius of better than 50nm. Post etching techniques can even sharpen the tip down to a <1nm tip radius. These sharp tungsten tips can be mounted to quartz tuning forks for AFM or for other types of scanning probe microscopy like scanning tunne领 microscopy (STM).
There are a variety of methods to choose from to etch the tungsten wire. The single lamella technique is easy to setup and can consistently produce sharp tips. Among the requirements for this process are a metallic ring, a beaker, Potassium Hydroxide (KOH), tungsten wire, and a voltage source. A drop of KOH is added to the metal ring suspended above the beaker, forming a thin film or lamella of KOH inside the metallic ring. The negative terminal of the voltage source is then connected to the suspended metallic ring. This will form the negative electrode. The beaker below the ring is then filled with KOH and the positive terminal of the voltage source is wired intod the KOH solution. This forms the positive electrode. The tungsten wire is then dipped through the center of the lamella and into the KOH in the beaker. The voltage source dis then turned on which begins the etching process. The tungsten is electrochemically etched at the lamella. The etching process automatically stops when the tungsten wire is etched so thin that the portion of wire below the lamella falls off and drops into the beaker. The remaining tungsten wire above the lamella is removed and any remaining KOH or contaminants are rinsed off with distilled water. This leaves a very sharp tip suitable for use in AFM or other types of SPM.
Mad City Labs provides an SPM Etch Kitalong with an application note on etching Tungsten tips to make this easy.Additional Information
