- high voltage mode scan size: 1.2um
- high voltage mode resolution: 0.2Å
Based on specific demands other scanning ranges can be set by the user in different configurations.*
Translator stage data:
X-Y range: 5 x 5mm
Z range: 13mm (4mm servo assisted)
STM Head
STM head with tip holer.
The head houses low current pre-amplifier with 1x10^9 V/A gain that make possible to get images from 2pA to 2nA. Other pre-amplifiers with different gain are optional on request.
Sample bias: -10 to +10V with step size < 1mV.
SPMCU-T
SPM Control Unit
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 provide by hardware timing.
HVA3-T Unit
HVA is an high voltage amplifier module projected to drive A-100 Heads.
Acquisition software
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.
Accessories:
pA-STM can be equipped with additional tools to enhance the instrument capabilities.
