Air handling systems, exhaust systems, toxic gas delivery, and monitoring systems will be down beginning at 7 a.m. Monday, October 7 through 4 p.m. Friday, October 11. The BNC staff will be performing appropriate preventive maintenance on the process equipment at this time as well. All CLEANROOM research work will be suspended until the maintenance activities are completed and all systems are returned to normal. No one will be allowed to enter the cleanroom during this time period. In addition, the laboratory areas will also be affected by this systems maintenance. As such, all LABORATORY activities that involve exhausted hoods, vacuum systems, and/or toxic gas systems will be down beginning 9 a.m. Monday, October 7 through 4 p.m. Friday, October 11. However, work that involves taking standard electrical measurements may be carried out in the LABS provided that fluctuating air temperature and humidity do not affect the readings. No chemical work will be allowed during this period. It is anticipated that the building and process tool maintenance will be completed by the end of the day on Friday, October 11. Please check Coral for equipment status and availability. Thank you, Heather L Anthrop Purdue University Birck Nanotechnology Center 1205 West State Street West Lafayette, IN 47907 (765) 494-7053

Please check Coral for equipment status and availability. Due to the new lab expansion projects electrical outages are required that will mainly affect the office areas. We will send out a notice with a date and time of the power outage when we have more detailed information from Physical Facilities. For long term research planning please refer the following future dates for our future preventive maintenance shutdowns. * Week of May 5, 2014 (Possible power outage of lab research tools) * Week of October 13, 2014 * Week of May 4, 2015 * Week of October 12, 2015 * Week of May 2, 2016 Thank you for your cooperation and understanding during these important preventive maintenance shutdowns. BNC Management ***Special Notice*** Dear Purdue Volunteers, Wanted to pass along this link to sign up for projects for United Way Week of Caring! There are 37 projects needing volunteers (throughout the community). They usually take just a few hours and a few volunteers. See details below. Thanks for your support for Purdue United Way! Sheryl Willison The following links will provide you access to the projects: First, you can go directly to the page with instructions and the projects listed toward the bottom at: http://volunteer.truist.com/uwgl/user/events/one.tcl?event_id=10596103596 Second, you may return to the Events section at any time and to get to the instruction and project page, click on "Learn more" under the Week of Caring in the Events section at: http://volunteer.truist.com/uwgl/volunteer Once you are on the instruction/project page: * Scroll through to look at a thumbnail description of the project; * To view a more detail about the project, click on the project title in blue; * If you want to choose this project, click on the word "Register" in blue (the project only shows one participant needed but this means one project available so only your organization can choose it. There are a few with multiple participants needed as those are projects that multiple organizations can do.); * You will then be prompted to fill in your information i.e.- name, phone, email address; * You will get an immediate response that you are registered and then an email that you are approved with further instructions. There are several projects to choose from and if you have any questions, please let me know. I would be happy to answer questions or help you through the process. Thank you for considering giving your time and talents to the Week of Caring. The agencies really look forward to this every fall and appreciate all the quality volunteers you provide!

Coffee/Ice Tea hour TODAY 3:30pm in the BNC Atrium
by Turner, Jaime J 23 Aug '13

23 Aug '13

Dear all, Please join us today in the atrium at 3:30pm - 4:30pm for a combined BNC/NSAC coffee/ice tea social hour. NSAC will be providing the ice tea for the social hour as well as biscuits today. Please remember to give them a big thanks while there! Every Friday during the fall and spring semester we will have this combined social hour. The coffee for it come from donations, the K-cups for this week's coffee hour have been donated by a BNC faculty and staff member. In order to keep these social hours alive and be able to enjoy a cup of coffee we ask that any BNC faculty or staff who would like to donate K-cups for it please do so by either 1) bringing a box(s) of K-cups to Jaime Turner (BRK 1027) or 2) donating money for them and Jaime can go buy the K-cups. Thank you and we hope to see you there! Jaime Turner Birck Nanotechnology Center Purdue University 1205 West State STreet West Lafayette, IN 47907-2057 (765) 494-3509 jjturner(a)purdue.edu

Condensed Matter Seminar - Dept of Physics

[Department of Physics] Condensed Matter Seminar Friday, August 23, 2013 3:30 PM, Room 203 Physics (Refreshments 3:00 PM, Room 242) Professor Paul Harrison [Paul_Harrison] University of Leeds United Kingdom School of Electronic & Electrical Engineering, University of Leeds, United Kingdom Surface Acoustic Wave Modulation of Quantum Cascade Lasers Quantum cascade lasers are n-type unipolar semiconductor heterostructure lasers fabricated many repeats of an active region unit cell that is itself comprised of several quantum wells. The electron energy levels and lifetimes within an active region are engineered to create a population inversion between two levels which when coupled with a resonant cavity or waveguide can lead to gain (amplification). GaAs-based devices give quantum wells that are one or two hundred meV deep and hence transitions between electron states are typically in the mid- or far-infrared (Terahertz) regions of the spectrum. These wavelengths have already been shown to be useful for chemical and biological sensing. It is then of interest to achieve precise and continuous dynamical tuning of the laser wavelength, certainly within limits set by the active transition linewidth. One possibility for this is to employ the distributed feedback (DFB) lasers, rather than the conventional end-mirror resonator lasers, where the distributed feedback would be provided by gain and refractive index modulation caused by a surface acoustic wave. The latter are generated by applying alternating voltages to interdigitated metallic fingers deposited on the surface of the "transducer" part of the device, which produces a mechanical wave through the piezoelectric effect. This wave in turn modulates the electron density within the active region of the laser, hence the gain and the refractive index, providing an optical feedback. The operating frequency is tuned by changing the surface acoustic wave frequency, i.e. the DFB grating period. The laser intensity modulation is also possible via the acoustic wave modulation depth, i.e. its power. We report on simulations of this effect and the initial experimental measurements.

New Credit Card Order Process
by Turner, Jaime J 19 Aug '13

19 Aug '13

Dear All, With Mary leaving Birck, we have adopted a new credit card order process. The purchase request still needs to be brought to the business office first for account approval. If the order is being placed by a student, the credit card will be handed to the student and the student can place the order here in the business office from the student's desk. If the order is being placed by the faculty, they are welcome to take the credit card back to their desk to use. In both cases, any receipts will need to be returned with the credit card to the business office. Thanks so much for everyone's help!

What we make moves the world forward.
