Change of mail and package pick-up
by Totten, Mary J 15 Jan '14

15 Jan '14

Everyone, Starting next Tuesday January 21, 2014; Purdue mail services will be making only 1 mail and package pick-up a day. That means you must get packages and mail to us by 8:30AM every day if you want it to go out that day. Otherwise it will go out the next working day. This is a decision that was made by MMDC and we cannot make any changes to this schedule. I ask for your patience, and please try and plan ahead on any packages that need to go out. You can contact me for any questions. Thank you, Mary Jo Totten Birck Nanotechnology Center Discovery Park/Purdue University 1205 West State Street West Lafayette, IN 47907-2057 (765) 496-1173 "Strength does not come from physical capacity.

Final Exam Missing Equipment Seminar XPS Workshop Final Exam Mohammed Imrul Hossain Birck 1001 at 3:00 pm Monday, January 13th Intersubband Transitions in III-V Semiconductors for Novel Infrared Optoelectronic Devices Intersubband transitions (ISBTs) in the conduction band (CB) of semiconductor multiple quantum wells (QW) have led to devices, like quantum-well infrared photodetectors and quantum cascade lasers (QCL). Due to the complexities related to the valence band (VB), hole ISBTs have not been explored as intensively as their electronic counterparts. Absorption and photoluminescence due to ISBT in the VB have been reported for p-type Si-SiGe QWs but this material system suffers from significant challenges associated with the built-in strain of these lattice mismatched materials. The GaAs/AlGaAs material system is virtually strain-free and quite mature. We are investigating the properties of bound-to-bound inter-valence subband transitions in GaAs QWs with high Al composition barriers for mid-infrared emitters. Hole ISBTs are interesting because the polarization of the light emitted in heavy-to-light hole transitions is not restricted to the perpendicular of the quantum wells (unlike electron ISBTs in the CB due to selection rules), therefore surface emitting QCLs and ultimately vertical-cavity surface emitting devices are possible using these transitions. Moreover the valenceband offset for pure GaAs and AlAs is comparable with the conduction-band offset in the traditional InGaAs/InAlAs lattice matched to InP system. Very recently we have observed strong heavy to light hole absorption and heavy to heavy hole electroluminescence from ridge waveguide structures in the mid infra-red range. We are also working on dual wavelength mid infra-red QCLs in the InGaAs/InAlAs system lattice matched to InP. This may be useful in applications like differential absorption lidar where light has to be evaluated and compared at two different frequencies for environmental sensing application. Most approaches to multi-wavelength QCL operation involve the use of heterogeneous cascades. Our design involves a single type of active region to emit at two widely different wavelengths in the mid-infrared range. These results provide insights in the detail charge transport and optical properties of this design concept. We are currently investigating the possibility of this type of dual wavelength laser for inversionless lasing. Missing Equipment Please return the lab cart (similar to that pictured) to the second floor east wing. If you are using the cart and will need it longer please speak with Lisa Reece as soon as possible.

Busnaina, Ph.D. is the William Lincoln Smith Chair Professor and Director of National Science Foundation's Nanoscale Science and Engineering Center (NSEC) for High-rate Nanomanufacturing (CHN) at Northeastern University, Boston, MA. He is internationally recognized for his work on nano and micro scale defect (particulate and chemical) mitigation and removal in semiconductor fabrication. He also involved in the fabrication of nanoscale wires, structures and interconnects. He specializes in directed assembly of nanoelements and in the fabrication of micro and nanoscale structures. He served as a consultant on micro contamination and particle adhesion issues to the semiconductor industry. He has authored more than 470 papers in journals, proceedings and conferences. His research support exceeds 47 million dollars. He is on the editorial advisory board of Semiconductor International, the Journal of Particulate Science and Technology. He is a fellow of the American Society of Mechanical Engineers, and the Adhesion Society, a Fulbright Senior Scholar and listed in Who's Who in the World, in America, in science and engineering. He was awarded the 2006 Nanotech Briefs National Nano50 Award, Innovator category, the 2006 Outstanding Faculty Research Award, Northeastern University 2006, the 2005 Aspiration Award, Northeastern University. The NSF Center for High-rate Nanomanufacturing (CHN) has developed a novel reconfigurable manufacturing technology platform that operates at ambient temperature and pressure, is water-based, material-independent and low energy, and requires small capital investment. It has been used to make structures and devices across length scales. The center has developed templates with nanoscale features to assemble and print structures down to 20 nm in a short time and over a large area. Recently, a rapid and scalable manufacturing process for 3D nanoscale features was developed to fabricate interconnects and plasmonic devices using nanoparticles. Nonvolatile memory switches using CNTs or molecules assembled at wafer level is one application. Another application is a new biosensor chip (0.02 mm2) capable of simultaneously detecting multiple biomarkers. The biosensor can be in vitro or in vivo with a detection limit that is 200 times lower than current technology. The center also developed several CNT and MoS2 based electronic devices. The center develops the fundamental science and engineering necessary to manufacture a wide array of applications ranging from electronics, energy, sensors and materials to biotechnology. A directed assembly-based nanomanufacturing factory could be built for as low as $50 million, a fraction of today's cost, making nanotechnology accessible to millions of new innovators and entrepreneurs and unleashing a wave of creativity in the same way as the advent of the PC did for computing.

Nitrogen Issues at Birck
by Reger, Ronald K 07 Jan '14

07 Jan '14

Dear All Birck Colleagues, Today we ran out of liquid nitrogen at Birck due to the severe weather which caused travel and delivery problems with our LN2 supplier. Gaseous nitrogen is produced from the LN2 so we ran low on gaseous utility nitrogen pressure as well. This caused issues with the UPW system and other valves which rely on utility nitrogen. Birck staff and trades we were able to temporarily plumb clean dry air as a substitution for the utility nitrogen, and return pressure levels to normal. We had to temporarily close the cleanroom tonight until the entire staff can get to work and fully assess the situation and implications of using CDA in this way. We will know more and have a short-term direction tomorrow. The real solution is to fill our LN2 tank, which will hopefully happen this week when Linde gets caught up with their delivery schedule. Thanks for your support, Ron
