Sample Holder with 13 electrical contacts and temperature sensor
Product code: SHOMEC13(LTDT)
A temperature sensor where you really need one: Right on the back side of your sample
Accurate temperature measurement is usually problematic with transferrable sample plates. Here, a DT-670 silicon diode is placed right underneath the sample mounting plate. By re-machining the sample mounting plate for a specific sample, it becomes possible to bring the temperature sensor even in direct contact with the actual sample. Full specifications of DT-670 sensors can be found here:
Reproducible positioning due to kinematic snap in mechanism
Flag style sample plates are commonly used in many home built and commercial UHV surface science instruments and scanning probe microscopes. The standard holders have the disadvantage of non-reproducible positioning when placed into their receptors. In order to overcome this problem, we have introduced three slits in the sample plate, while keeping the outline dimensions and compatibility with existing transfer systems and receptors. If placed into the corresponding receptor which features three ruby spheres, our modified SHOM snaps in reproducibly with a precision in the micrometer range.
Up to 13 electrical high quality spring contacts for wiring up devices
The SHOMEC13 features a total of thirteen high quality spring contacts mounted into an AlN-isolator. The shape and opening of the top plate and shield cover can be customized to your needs.
Molybdenum base plate and shield cap for high thermal conductance and low CTE
Molybdenum and Shapal M both feature a relatively high coefficent of thermal conductivity between 100-140 (W/m/K) (@20C). Coeffcients of thermal expansion of Mo and Shapal are well matched at 4.8 for Shapal and 5.35 (10E-6/K) for Mo. All selected materials are suitable for cryogenic temperatures and UHV.
