Surface Analysis Center
Facility Location
0508/0504, Chemistry Building 091
Brief Mission
The surface analysis center houses state-of-the-art instrumentation and provides services for surface analysis including X-ray photoelectron spectroscopy (XPS), confocal Raman and atomic force microscopy (AFM). The facility is staffed by experts and is managed on a fee-per-service basis. The facility is open to academic, government, and industrial users.
Hours of Operation
Normal hours of operation are 9 AM to 5 PM, Monday through Friday. Trained users with University ID's are able to activate their ID's to gain access to their run samples on the instruments after hours and weekends.
Services and Technologies Offered
Generally users are trained on the Raman and AFM, after training the user is able to reserve the instrument through an online booking system, and use the instruments unsupervised. XPS samples are generally run by the center staff, users would normally drop off samples and pick up data but training is available for regular users.
Equipment Available
XPS
- The Kratos Axis Supra+ was installed in May 2023 and is currently the newest addition to the SAC. This instrument brings new capabilities to the lab including hard x-rays and cluster depth profiling as well as powerful imaging capabilities. In addition to XPS the instrument also has additional techniques and capabilities including UPS, AES, SEM/SAM, REELS, ISS and a gas reaction cell.
- Kratos Axis 165 Photoelectron Spectrometer, with Al monochromatic x-rays as well as a dual Al/Mg source, Argon iron sputtering, and charge neutralization capabilities.
Confocal Raman
- Horiba Jobin Yvon - Labram Aramis, equipped with swift and stage mapping options allowing rapid collection of mapping with the highest possible resolution. Laser wavelengths available are 532 nm and 633 nm.
AFM
- Digital instruments, Multimode, Nanoscope III, with phase imaging capabilities and fluid cells for liquid AFM.The Asylum Research Cypher-ES AFM can provide controlled gas/liquid/humidity environment. It’s also capable of heating (250 ℃), cooling-heating (0~120℃) and high voltage (+/- 220V). Advanced capabilities include high speed AFM with blue drive, SKPM, Conductive AFM, MFM, EC-AFM, AM-FM, EFM, PFM and microangelo nanolithography/nano manipulation.
- The Asylum Research MFP3D AFM when compared to Cypher is a larger sample AFM handling larger and rougher samples and is capable of XY scan sizes up to 90 microns.
