Low Temperature Ultra High Vacuum Scanning Tunnelling Microscope Ultrascan LT-100

Cryogenic ultra-high vacuum scanning tunnelling microscope STM (Ultrascan LT-100), scanning probe microscope (STM) as a representative of ultra-high vacuum equipment, is widely used in scientific research, mainly to carry out the atomic-scale study of all physicochemical phenomena related to or occurring on the surface. The ultra-high vacuum cryogenic (4K) STM system developed includes key technologies such as piezoelectric ceramic stepper motors, cryogenic STM probes, and ultra-vacuum liquid helium double-layer dewars.

The Low Temperature Ultra High Vacuum Scanning Tunnelling Microscope is a high-precision research tool that integrates cutting-edge scientific technologies, providing a reliable platform for exploring surface structure and electronic properties at the atomic level. It maintains an ultra-high vacuum environment to protect sample surfaces from contamination, while utilising extremely low temperatures to effectively reduce thermal noise and surface activity, enabling stable observation at the atomic and molecular levels. This instrument not only serves as a “microscopic eye” for researchers studying the microscopic world of matter but also serves as a key tool for advancing the development of materials science, condensed matter physics, and nanotechnology.

Core Performance Advantages

• Atomic-level resolution: Leveraging the scanning tunnelling effect, it can clearly capture the arrangement of individual atoms and the distribution of localised electronic states on a surface.
• Cryogenic Environment Control: Operating in liquid helium or liquid nitrogen significantly reduces noise, achieving higher stability and imaging accuracy.
• Ultra-high vacuum conditions: Effectively eliminate interference from air molecules, ensuring a pure and long-term stable sample surface.

These advantages not only provide powerful imaging capabilities but also make it an ideal platform for interdisciplinary research.

The Low Temperature Ultra High Vacuum Scanning Tunnelling Microscope has been widely used in research on quantum materials, superconductors, two-dimensional materials, and surface catalysis.

It can help researchers analyse electronic band structures, explore the distribution of quantum states, and even drive the development of future information and energy technologies.

For university laboratories, research institutes, and cutting-edge industry R&D departments, this device is not only an experimental tool but also a vital support for scientific breakthroughs.

Choosing this type of high-end microscope means standing at the starting point of exploring the origins of matter and the forefront of future technologies.
