Surface Analysis Laboratory (SAL)

Who we are
The Surface Analysis Laboratory specialises in advanced surface characterisation using X-ray Photoelectron Spectroscopy (XPS), Ultraviolet Photoelectron Spectroscopy (UPS), and Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS). These techniques enable precise determination of elemental and chemical composition, spatial distribution, and molecular structural identification of the outermost layers (the first 5–10 atomic layers) of solid surfaces. The lab is also equipped to measure variations in composition with depth, providing a comprehensive understanding of multilayered structures and interfaces.
With state-of-the-art instrumentation and extensive technical expertise, the Surface Analysis Laboratory delivers high-quality, detailed surface characterisations to support research, innovation, and materials advancements across scientific and industrial applications.

Capabilities
Instruments
-
Time-of-flight secondary ion mass spectrometer for molecular and elemental surface analysis using a bismuth cluster analysis beam. Elemental and isotopic imaging down to 100 nm lateral resolution, and Angstrom-resolution depth profiling (cesium, oxygen and argon-cluster ion beams) is also available from this instrument.
-
Thermo ESCALAB250i high-resolution X-ray Photoelectron Spectrometer (XPS) using a monochromatic Al Kalpha soft X-ray source, a monoatomic argon ion beam for depth profiling, variable-temperature stage, and He UV Source for ultraviolet photoelectron spectroscopy.

To start the onboarding process, simply sign up to UNSW's ACLS booking system (button below). Once registered you can choose Surface Analysis Laboratory from the list of facilities to reserve time on the instruments.
-
Once you have completed the registration, you'll get an email detailing the next steps for onboarding. This email will include a link to a form where you can describe your project. Based on your needs, we will tailor a team to meet with you and address your requirements.
-
During this meeting, we will explain how to gain access to our lab space and what training will be required. Additionally, we will discuss your research project to match you with the most suitable instrument for your research question.
-
Access will be granted once you complete your online lab induction and receive in-person training from our staff on all relevant instruments. Our training is thorough and designed to accommodate individuals who have no prior experience with technical equipment.
-
Surface analysis involves the analysis of the top 1-10 nm of the sample; thus, it is extremely sensitive to any sample preparation treatments. There is typically a residue related to any pre-treatment of the sample, and "adventitious" (or environmental) contamination in the form of compounds absorbed onto material surfaces from the atmosphere might always be present.
In general, we analyze samples "as received." Guidelines on how to prepare your samples for the best outcomes are available in the sample preparation document.
-
Surface Analysis Lab provides free access for users to submit samples and request forms from 8am-6pm on workdays. You can drop off your samples and request form on our sample submission table during this time. We will do the analysis for you.
-
Results will be available within one week from when your samples and request form are well received.
