Scanning Tunneling Microscope(STM)
Scanning tunneling microscopy (STM) has proved to be an invaluable tool for probing different surfaces and providing both topographic an spectroscopic information with atomic- scale spatial resolution.
Digital Data Input Output
Specification:
Scanning stage with Piezoceramic Tube.
X-Y piezo tube:
high voltage mode scan size: 10 x 10 μm;
low voltage mode scan size: 650 x 650 nm
high voltage mode resolution: 1.5 Å
low voltage mode resolution: 0.1 ÅZ piezo tube:
high voltage mode scan size: 1.2 μm
high voltage mode resolution: 0.2 Å
STM Head
Specification:
- The Head houses low current preaplifier with 1·109V/A gain that make possible to get images from 2pA to 2nA. Other preamplifiers
with different gain are optional on request.
Sample bias: -10 to +10 V with step size < 1 mV
SPMCU-T
Specification:
- SPM Control Unit and PC (equipped with a multi input-output board) drives the scanner, data acquisition and sample motion.
Tip to sample distance is controlled by ultra-low noise analogue feedback, digitally driven by PC. High speed and temporal precision are provided by hardware
timing.
HVA3-T Unit
Specification:
HVA is an high voltage amplifier module projected to drive A-100
Heads.
HVA3-T Unit
Specification:
Software runs under Windows and is composed of a multi-window
applications for instrument control and data acquisition. The
software comes equipped with simple filters for immediate analysis
of acquired images. The software controls all the parameters of the
instrument.
HVA3-T Unit
Specification:
- pA STM can be equipped with additional tools to enhance the instrument capabilities.
