Part of the ventilator. 

A team led by the University of Illinois at Urbana-Champaign’s Grainger College of Engineering and Carle Health has produced a prototype emergency ventilator to help address the expected surge in the need for respiratory care associated with the COVID-19 pandemic. Holonyak Lab's Rashid Bashir, Stephen Boppart, and Matt Wheeler are part of the 50+ person team working on this effort. Read more

Crumpled graphene 
Liz Ahlberg Touchstone, Illinois News Bureau

Graphene-based biosensors could usher in an era of liquid biopsy, detecting DNA cancer markers circulating in a patient’s blood or serum. But current designs need a lot of DNA. In a new study, crumpling graphene makes it more than 10,000 times more sensitive to DNA by creating electrical “hot spots,” researchers led by Holonyak Lab's Rashid Bashir found.

Grants and Gifts

No new gifts or grants reported for this month.

New staff introduction
Elbashir Araud 

Introducing Holonyak Lab’s newest Research Scientist, Elbashir Araud
Araud’s area of expertise is in virology and microbiology, with emphasis on inactivation technologies of enteric human and animal viruses. His previous research is focused on determining the mechanisms by which High Pressure Processing, UV and solar irradiation, and cold plasma inactivate pathogenic viruses. He worked on developing methods to differentiate between infectious and noninfectious viruses in food and environmental samples. Araud received his Ph.D. in Veterinary Biosciences from The Ohio State University.

Equipment update

Equipment ordering update

We are finalizing the purchase and will update you with more information soon.

Oxford Plasma Pro 100 ICP-RIE Etcher
The Oxford Plasma Pro 100 will replace the Plasma-Therm ICP, with many new benefits for users, offering both Chlorine and Fluorine chemistries with minimal tool restrictions. It has eight gas channels: Cl2, BCl3, SF6, CHF3, O2, Ar, N2, and H2. It is equipped with atomic layer etching capability for slower and controlled etching for thin etching, and is estimated to ship in late June.

Oxford Plasma Pro 80 Reactive Ion Etcher
This tool, equipped with 600W RF platen source, will replace the existing Freon RIE. It has six gas channels: SF6, CHF3, CF4, Ar, O2, and N2. The estimated shipping is in late June. 

Elionix Electron Beam Lithography System
This system, which is the only 150 KeV EBL in North America, will ship in November.

DektakXT stylus profiler
The DektakXT, expected to arrive in June, will allow for better surface information for steps and features and enables easier room temperature stress measurements and verification of stress, in conjunction with the existing variable temperature system.

Processing tips

HMNTL is pleased to introduce a new webinar series that aims to help share knowledge about the cleanroom equipment and processing technology with users. The first webinar will be held at noon on Tuesday, April 14. For more details on individual sessions, please refer to the Events section below.

Facility information
Building access and fees

During the COVID-19 stay at home executive order, the Holonyak Micro and Nanotechnology Laboratory has several ongoing research projects to develop technology related to COVID-19. These projects are ongoing in the shared-use bionano laboratory and require strict safety protocols for the limited number of essential workers approved to work on this project. 

HMNTL users will not be charged the Building Access Safety fee during the COVID-19 shutdown of Holonyak Lab associated with the Illinois-stay-at-home order. However, the Biolab users who are performing COVID-19 research will still be charged the fee as they have access to the lab.

New cleanroom user
If you are waiting for HMNTL to reopen the cleanroom, you can get a head start on access by beginning new user training now. There are several steps that must be completed, which are outlined on the HMNTL website at https://mntl.illinois.edu/facilities/cleanrooms/steps.asp. Then, please contact the business office (mntl-businessoffice@illinois.edu) to set up cleanroom training. Mark McCollum will provide training by video conference so that you can use the cleanroom when you return to campus, following a walk-through.

Postdoc opportunities
  • The Optical Sciences Division of the Naval Research Laboratory seeks a highly-motivated theoretical physicist or electrical engineer to fill one of two positions: (1) a National Research Council (NRC) or American Society for Engineering Education (ASEE) post-doctoral Research Associateship or (2) a graduate or undergraduate student for part-time or full-time employee. For the full job listing contact Jerry R. Meyer, Navy ST for Quantum Electronics.
  • T.P. Ma of Yale University is looking for a postdoc to join his team and work on ferroelectric memory devices and/or circuits. The ideal candidate should have a strong interest in emerging semiconductor memories, and background in semiconductor devices physics, as well as expertise in device characterization and analysis. Interested candidates should email T.P. directly and applications will be reviewed as soon as practical.
