Troy, MI, September 22, 2014 – The PanScan-Freedom LT is an innovative new closed-cycle cryogen-free system for stable low temperature performance, unprecedented low drift, exceptional spectroscopy performance, and atomic resolution in a surprisingly compact, simple, and affordable package.  PanScan-Freedom LT system features 15 K to 400 K operation without the expense and frustration of using liquid cryogens.  PanScan-Freedom LT redefines helium-free low temperature performance, with an unprecedented XY drift as low as 0.2 Å/hour and Z drift as low as 0.2 Å/day.

RHK is to unveil the PanScan-Freedom LT at the 2014 AVS 61st international meeting being held in Baltimore, November 9-14. Visitors to the conference may see the system first hand in booth #410. (www.avs.org/Meetings-Exhibits/Information)

PanScan-Freedom LT incorporates RHK’s purpose-built hardware, including the groundbreaking R9 control electronics, for lowest noise, highest performance, and industry leading cryogen-free low temperature performance.

Uniquely designed for easy adaptation, PanScan-Freedom LT can also integrate with existing chambers to provide an affordable, small footprint LT UHV SPM station on other analysis or process instruments already in place in a laboratory.  The clever design of the closed cycle module also provides an easy upgrade path for existing PanScan systems, protecting the customer’s investment in their research.

RHK Ships 100th R9 Control System
02.17.14
TROY, MI February 17, 2014

RHK Technology, Inc. announced shipment of its 100th R9 Control System for Scanning Probe Microscopes. The latest in RHK’s long history of advances, R9 breaks new ground with its revolutionary design: a totally integrated AFM/STM single-box solution. R9 combines all-digital, ultra-fast, ultra-low-noise electronics with an interface tailored especially for SPM scientists.

Observing the 100-unit milestone, Adam Kollin, RHK President and driving force behind R9, said, “We’re very proud to achieve this so quickly. The number of R9 just keeps climbing, along with very positive feedback from nanotech researchers around the world. We built R9 to be the best and it’s proving so every day.”

R9 Product and Tech Support Manager Ken Kollin added, “Customers appreciate the unique depth of capability plus ease of use R9 provides. Soon we’ll add even more with free upgrades for deeper automation with LabVIEW and MATLAB, advanced drift correction, new spectroscopy modes, and additional PLLs and lock-in amplifiers.” To mark the milestone, RHK is holding live R9 Webinars and demonstrations world-wide.

Abstract: We use photoelectron spectroscopy, low energy electron diffraction, scanning tunneling microscopy, and density functional theory to investigate coverage dependent iodine structures on Pd(110). At 0.5 ML (monolayer), a c(2 × 2) structure is formed with iodine occupying the four-fold hollow site. At increasing coverage, the iodine layer compresses into a quasi-hexagonal structure at 2/3 ML, with iodine occupying both hollow and long bridge positions. There is a substantial difference in electronic structure between these two iodine sites, with a higher electron density on the bridge bonded iodine. In addition, numerous positively charged iodine near vacancies are found along the domain walls. These different electronic structures will have an impact on the chemical properties of these iodine atoms within the layer.
