A.P.E. Research developed several UHV STM systems for
Universities and research centers.
The systems have been designed to evaporate (e.g. metals, organic
molecules) in UHV directly on the sample mounted on the STM head.
The systems allow to perform measurements of the same region of the
surface at different stagesof growth. In this way it is possible to
make a “movie” of the same scanned area as
deposition time proceeds.
The STM head, designed and crafted by A.P.E. Research, features an
innovative inertial stage for coarse approach which allows STM tip to
reposition on a spot with a resolution better than a few tens of nm.
SPM Control System
- is composed by a digitally controlled analog feedback
that combines the flexibility of computer controlled parameters with
the high resolution and low noise of an analogue implementation. The
electronics supports STM, AFM and SNOM heads, performs different kinds
of spectroscopy and can acquire several user-defined auxiliary channels.
- Software runs under Windows and is composed of multi-
window applications to control the instrument and perform the data
acquisition. The software controls all the parameters of the
instrument (see
>>).
