We are excited to announce that the new  PHI Genesis XPS (X‑ray Photoelectron Spectroscopy) system is now available for user access at Nano3.

This fully automated, multi‑technique scanning XPS/HAXPES system brings cutting‑edge surface analysis capabilities to our user community.

Some of its key features include:

• Dual monochromated X‑ray sources (Al and Cr) for greater analytical flexibility and deeper information depth
• High‑resolution microprobe (<5 µm for Al and <14 µm for Cr sources)
• Depth profiling with multiple ion gun options (monatomic Argon, Argon cluster)
• Fast automated switching between XPS and HAXPES modes
• Ultraviolet Photoelectron Spectroscopy (UPS) 
• LowEnergy Inverse Photoelectron Spectroscopy (LEIPS)
• Reflection Electron Energy Loss Spectroscopy (REELS)
• Auger Electron Spectroscopy (AES)
• Hot/cold stage with a temperature range of -100 °C to 500 °C
• XPS on air-sensitive samples

We invite all users to explore the capabilities of this new advanced system. Please submit your training request on the PHI Genesis Scanning XPS via FOM. Look forward to seeing the exciting research this powerful new tool will make possible.

To further enhance safety and accountability within our facility, we are introducing a new requirement for all Nano3 Cleanroom users. Starting on 11/17/2025, all cleanroom users are required to wear a user identification badge whenever they are in the cleanroom.

Your identification card will need to display 4 letters composed of your name:

• The first three letters of your first name and the first letter of your last name (e.g., MICJ for Michael Johnson).
• If your first name has fewer than three letters, please use your full first name and add the first one or more letters of your last name to make a total of four letters (e.g., ALWA for Al Wang).
• Use the Word (.docx) document sent to you by email to print your name card on paper and cut it so it can fit the sealable badge holder. You can also download the template document from: https://nanofab.ucsd.edu/resources/
• The font should be Agency FB, bold, with a font size between 110 and 130, to ensure consistency across all user badges. The four letters should fill the rectangular shape in the provided template as much as possible.

We will provide sealable badge holders in the pre-gowning room for you to insert your identification card. After inserting your name card, make sure to seal the badge holder completely. This is important to prevent any loose fibers or particles from the printed card from entering the cleanroom environment. Bins will also be available in the gowning room for convenient badge storage when not in use.

Nano3 staff members, including student assistants, will have their names printed differently. Their names will appear on colored tapes rather than on papers. This distinction will make it easy for users to identify staff members inside the cleanroom. The color of the tape may vary depending on each staff member’s preference, but all staff name tags will follow the same general format.

The full implementation of this new badge requirement will take effect on November 17, 2025. After this date, users found not wearing their badge or using an incorrect badge format will receive one warning, followed by suspension of their Nano3 access for any subsequent offense.

We understand that implementing new procedures takes time, so we encourage everyone to begin complying next week or as early as possible. Your cooperation in adopting this new policy will help us maintain a safe, professional, and well-organized environment for all users. Thank you for your attention and continued support.
