Сканирующий туннельный микроскоп
The Nanosurf Easyscan 2 is a modular scanning probe microscopy system that offers flexibility at a great price: one controller, several scan head types, and various upgrade possibilities! Meant to resolve atomic structures at the surface of electrically conductive materials, this easy-to-use and compact, scanning tunnelling microscope is particularly suitable for training purposes. The complete system includes a probe for row-by-row scanning of sample surfaces with the measuring tip, vibration-absorbing pad, controller with computer interface, as well as graphite and gold samples.

Experiment topics:

  • Tunnel effect

  • Representation of individual atoms

  • Representation of lattice defects and dislocations

  • Representation of charge density waves

  • Dependence of tunnel current on distance between measuring tip and sample

  • PID control of tunnel current

System requirements:

  • Windows 2000 or higher

  • XYZ grid: 500x500x200 nm?

  • Minimum increment XY: 7.6 pm

  • Minimum increment Z: 3 pm

  • Tunnel current: 0.100 …100.000 nA (0.025 nA increment)

  • Voltage: ±10.000 V (0.005 V increment)

  • Maximum sample size: 10 mm diam.

  • Supply voltage: 90 – 240 V, 50/60 Hz

  • Connection: USB

Scope of Delivery:

  • Controller

  • Installation CD with measurement and control software

  • Scanning probe with connection cable

  • Cover with lens

  • Experiment plate with vibration damping

  • Tool kit for manufacturing the probe tip (side cutters, flat-nose pliers, pointed and rounded tweezers)

  • Platinum-iridium wire, 0.25 mm diam., 300 mm

  • Graphite (HOPG) sample on a carrier

  • Gold (1.1.1) sample on a carrier
