Used TAKAYA APT 8400 CD #9035123 for sale

TAKAYA APT 8400 CD is a scanning tunneling microscope (STM) prober designed to achieve sub-nanometer resolution in the study of the electrical properties of solid surfaces and nanoscale systems. This system utilizes a high-resolution scanning tunneling microscope to enable precise measurements and imaging at the atomic scale. APT 8400 CD utilizes a unique design that provides not only increased precision and resolution, but also improved electrical isolation and cooling capabilities for advanced studies. The prober's design consists of an STM head assembly attached to a precision stage, and its components allow for the accurate fine tuning and stabilization of the microscope's operation. The piezo-driven x and y axes, as well as the z-axis approach, allow for controlled movements in all three dimensions.The prober's piezo-driven sample rotator and z-axis approach compensate for rotation and sample-z movement, reducing both drift and vibration noise. This combination of precision and stability gives TAKAYA APT 8400 CD exceptional performance and allows it to achieve a resolution of 0.2 nm in the z-direction and 0.4 nm in the xy-direction. The prober is also equipped with a range of critical electronics that ensure smooth operation, including a dedicated signal amplifiers, low-noise preamplifiers, a DSP controller, and advanced software controls. The DSP controller, along with the computer-controlled voltage regulator, reduces drop-out noise that can interfere with STM measurements. Furthermore, the prober's low noise environment and fast response of the DSP controller enable reliable data acquisition. The prober also incorporates various features to help improve the accuracy and repeatability of STM measurements. The internal feedback loop monitors the tip-sample interaction at a data rate of up to 100 Hz, helping to stabilize the tip/sample interaction and reduce contact noise. The automated tip approach and scanning functions ensure accurate and repeatable measurements. Overall, APT 8400 CD prober is a sophisticated piece of equipment that provides accurate and precise measurements of electrical properties at the nanometer-scale. Its features enable high accuracy and repeatability, combined with fast operation and low noise operation.
