Six research groups are highlighted that utilized RHK’s PanScan SPM head to overcome the challenges of time, funding, and unique requirements. They successfully built custom UHV SPM systems as varied as cryogen-free, LHe bath, and even 300 mK -- plus high magnetic fields. Cutting-edge results were achieved and published in high-impact journals.
Cryostat can be rotated inside of in-plane field to allow nanowires on surface to be aligned with 5T field. Scan head can be transferred between ambient temperature and mK stages for ease of sample/tip exchange and verification of sample before expending helium to cool down the scanner head.
Four PanScan heads in four applications. Ten years ago first scanner went into new homemade 4K system. Later two scan heads were used to replace older student-built microscopes. A new RHK-developed custom microscope utilizing in-situ exchangeable optical fiber probes is under development.
PanScan SPM integrated into a homemade cryostat. The scan head is mounted to the bottom of the 4K dewar without any vibration isolation and able to routinely acquire high quality noise-free data. A second PanScan head is on order that will be dedicated to qPlus atomic resolution studies.
Pan Scan system was purchased as an ambient environment SPM then upgraded in stages to room temperature UHV operation and then to UHV 9K cryogen-free operation. The system design allowed these upgrades without any change to the scan head of chamber.
PanScan SPM integrated into Cryo Industries 4K cryostat. The scan head was the core technology of a homemade system that was part of a start-up package. It has been running reliably and producing high quality data for seven years.
Two PanScan heads integrated into two different systems. One scan head replaced obsolete student-made scan head in UHV cryogenic application. Second scan was integrated into a new UHV system designed to study initial stages of laser-induced ablation, starting from single defect level up to fully periodic surface structures.
