Small Business Innovation Research Program Provides Seed Funding for R&D

RHK Technology has been awarded a National Science Foundation (NSF) Small Business Technology Transfer (STTR) grant, in conjunction with Prof. Gang-yu Liu at University of California, Davis and Prof. Darrin Hanna at Oakland University, to conduct research and development work on a smart and fast SPM controller and microscope add-on for automatically finding dynamic features, scanning them at ultra-high-speed scan rates, and providing true material mechanical properties.  These achievements will expand AFM significantly, especially in the fields of nanodevice inspection and quality control, nanolithography, tissue engineering, and development of nanomaterials; an exciting leap forward.  With designing the microscope add-on proposed in this work to fit existing microscopes, thousands of scientists will have the option to utilize smart and fast scanning with their existing equipment.  The features provided in this smart and fast AFM will add important capabilities for imaging and characterization that will be used by professionals dedicated to engineering the future in research and development institutions and departments worldwide.

RHK Technology has recently installed the first PanScan Freedom AFM/STM system with their latest cryostat option, offering a 9K base temperature. The system was installed at the University of New Hampshire, in the laboratory of Prof. Shawna Hollen.   Besides the standard PanScan Freedom architecture, this unique system included a custom preparation chamber designed to provide a five-point probe measurement station, having three degrees of freedom for probe positions. It has also been equipped with a top-view port for probe positioning.

“I chose the PanScan Freedom after seeing the technology both at APS 2015 and the RHK factory. The ability to continue my low-temperature research without the concerns of sourcing liquid cryogens was one of the deciding factors. Working with the RHK team has been great so far, and my students really appreciated the time and care the installation scientist spent training them. We look forward to executing our research exploring the properties and functionalization of 2D materials using the unique tools developed by and with RHK.” — Prof. Hollen 

RHK Technology looks forward to installing many more of these systems in the coming months, with installations planned in China, Germany, Australia, and the USA. RHK Technology will also be demonstrating the 9K PanScan Freedom system at the upcoming APS meeting in Baltimore, MD. To thank it’s customers for their continued support, there will be a users reception to be held at the Hilton Baltimore during the annual APS meeting. Stop by booth 510 to ask about the details.

The team at RHK Technology is excited to announce the launch of the new 9K PanScan Freedom System! Customers will now have the option to choose between the 15K and 9K versions of our cryogen-free SPM systems.

9k Pan Scan Freedom

One year ago, RHK Technology launched the first commercial closed-cycle SPM system. At that time, the system could achieve a tip/sample base temperature of 18K.   Over the last year, the PanScan Freedom has become the most successful microscope system in RHK’s history. During that time, our engineers, led by Dr. Byoung Choi, have worked tirelessly to further optimize the design. This resulted in the original version of the system achieving a 15K base temperature, without any sacrifice to resolution or drift.

Through our close collaborations with the researchers in this field, we knew that delivering a system that could consistently perform below 10K would open up an entire world of measurements. Both spectroscopic and morphological studies would benefit from this advancement.

The constant efforts by Dr. Choi and his team to refine every aspect of the damping, shielding, and thermal coupling allowed us to integrate a more powerful cryostat to the PanScan Freedom, once again without sacrificing performance. The strength of the design becomes immediately apparent when you see the system performing in person, with the persistent pumping of the cryostat completely absent from the spectrum analyzer data. Seeing really is believing with the PanScan Freedom!

This 9K version of the PanScan Freedom will be launched at the 62nd Annual AVS Symposium in San Jose, CA. Attendees will have the opportunity to see a live demonstration over the three-day exhibition.
