LOW
TEMPERATURE PHYSICS MEASUREMENT SYSTEMS.
:.........................................................................................
Experience your new working horse in the emerging field of semiconductor
research for the nanoscale age. attocube systems presents its
product line of low temperature physics measurement systems.
Perform your experiments time efficiently resulting in your company‘s
future nanoscale products.
With this novel ultra-modular systems a variety of scanning
probe microscopy (SPM) techniques as well as a probing station
at low temperatures down to 300 mK can be covered within
one single device. This is realized by a modular basic system
in combination with flexible, high end control electronics supporting
your individual research task. For this system, a variety of
microscopy inserts are available which are tailored for your
individual measurement tasks and can simply be expanded for future
projects. For details on the different microscopy and probe station
inserts, please refer to the ‘nanoSCOPY‘ and ‘nanoTOOLING‘ sections.

ultra-stable low temperature physics measurement
systems
The basic LTSYS-He4 systems are based on
a liquid Helium bath cryostat and optimized for highest
stability of
your measurements. Options as a variable temperature insert
(VTI), a He3 insert, or a dilution refrigerator unit,
enable to cover a large temperature range down to the mK
regime.
Superconducting magnets up to 15 T are compatible with
the system. The compatible microscopy inserts range
from Confocal Microscopy (CFM) and Scanning Nearfield
Optical Microscopy (SNOM) to Atomic Force Microscopy
(AFM) and related techniques (Magnetic Force Microscopy
(MFM) and Electric Force Microscopy (EFM), as well
as Scanning Tunneling Microscopy (STM) for measurements
with atomic resolution. Furthermore, probe station
modules for cryogenic probing of your NEMS/MEMS samples
are available.

cryogen-free low temperature physics measurement
systems
This cooling system includes a cryogen-free closed-cycle
cryostat for applications where liquid Helium is not
available or desired. Expensive running costs and security
issues can be avoided. An optional Adiabatic Demagnetization
Refrigerator (ADR), or dilution refrigerator unit enables
ultra-low temperature setups. The
automation level allows for ‘set and forget‘ operation
for non-expert users. For these systems, a variety of
Confocal Microscopy (CFM) inserts, the Atomic Force Microscopy
(AFM) insert with MFM and EFM functionality,
as well as the probe station inserts are available.
